Factors of 18 space the perform of integers that can be evenly split into 18. It has a full of 6 components of i beg your pardon 18 is the best factor and the positive factors of 18 are 1, 2, 3, 6, 9, and also 18. The Pair determinants of 18 space (1, 18), (2, 9), and also (3, 6) and also its Prime determinants are 1, 2, 3, 6, 9, 18.
You are watching: All factors of 18 that are prime
Let united state explore much more about components of 18 and also ways to discover them.

What room the factors of 18?
Factors that a number are the number that divide the given number specifically without any type of remainder. Follow to the definition of factors, the factors of 18 are 1, 2, 3, 6, 9, and 18. So,18 is a composite number as it has an ext factors various other than 1 and also itself.
How to Calculate determinants of 18?
We can use different methods choose the divisibility test, element factorization, and the upside-down department method to calculate the components of 18. In element factorization, us express 18 as a product the its element factors, and also in the division method, we see which number divide 18 exactly there is no a remainder.
Let united state calculate determinants of 18 using the complying with two methods:Factors the 18 by element factorization element tree methodFactors the 18 by upside-down division method
Prime administrate By Upside-Down division Method
Prime administer is to express a number as a product the its prime factors.For example, determinants of 6 room 1, 2, 3, 66 = 2 × 3So, the prime factors of 6 room 2 and 3.
The upside-down division got that is name because the department symbol is flipped upside down.STEP 1: By utilizing divisibility rules, we find out the smallest specific prime divisor (factor) the the given number. Here, 18 is an also number. So it is divisible by 2. In various other words, 2 divides 18 through no remainder. Therefore, 2 is the the smallest prime factor of 18.STEP 2: We divide the provided number by its smallest variable other 보다 1 (prime factor), 18 ÷ 2 = 93 is the quotient, so we stop the procedure here. Therefore, 18 = 2 × 3 × 3
Prime administrate by factor Tree Method
First, we recognize the 2 factors that offer 18. 18 is the source of this aspect tree.18 = × 6Here, 6 is a composite number. Therefore it have the right to be additional factorized.6 = 3 × 2We continue this procedure until we space left with just prime numbers, i.e., till us cannot further aspect the obtained numbers.We climate circle every the element numbers in the element tree. Basically, we branch the end 18 right into its prime factors.
So, the prime factorization that 18 is 18= 2 × 3 × 3.
A element tree is not unique for a offered number. Instead of expressing 18 as 2 × 9, we deserve to express 18 as 3 × 6. Right here is a straightforward activity to try on your own. Rather of 2 × 9, if I had offered 3 × 6, carry out you think we would get the exact same factors?Can you attract the variable tree through 3 and 6 as the branches?

Factor pairs room the 2 numbers that, once multiplied, offer the number 18.18 = 1 × 1818 = 2 × 918 = 3 × 6
Therefore, pair determinants of 18 are (1,18), (2,9), and also (3,6). A element rainbow helps you find every one of the factors. It is dubbed a rainbow because all of the variable pairs connect to do a rainbow! Making a variable rainbow is rather easy.
Let’s shot one:Find every one of the factors for the number 18.Step I: start with 1 and also the number itself.Step II: count up by persons to check out if you can multiply two numbers with each other to obtain your target number.Step III: Stop once you can’t gain any more numbers in between.Step IV: connect the variable pairs.
In total, we have actually 3 element pairs, i.e., there space 6 components of 18: 1, 2, 3, 6, 9, 18.
We have the right to have an adverse factors additionally for a provided number.For example: Since the product that two an adverse numbers is confident <(-) × (-) = +>.(-1,-18) , (-2,-9), and (-3,-6) are also factor bag of 18.But because that now, permit us focus on the positive determinants in this article.With factors, we are just looking for totality numbers that space equal come or less than the initial number.
Important Notes:Factors that a number are the numbers the divide the offered number exactly without any type of remainder.18 is a composite number as it has much more factors various other than 1 and also itself.Pair components of 18 are (1,18), (2,9), and (3,6).1 is a factor the every number.The factor of a number is always less than or equal to the provided number.Prime factorization is to express the number as a product the its element factors.
90 × 0.2= 18. Have the right to we finish (90, 0.2) as a aspect pair the 18?Is the variety of factors of a offered number finite?Can the factor the a number be higher than the number itself?
Example 2: There are 18 people in a room together at a party. Anyone would like to take component in games during the party. What might be the feasible sizes of groups we have the right to break the civilization into so that no one is left out and also everyone deserve to play?
To deal with this problem, we require to recognize the components of 18.List lock out: 1, 2, 3, 6, 9, 18.Let"s see just how the factor pairs can aid us.Factor pairs: (1,18), (2,9), (3,6)
The an initial pair, 1 and 18, doesn"t tell united state much. It just means that we could have 1 group of 18.
The second pair tells united state we can have 2 groups of 9 or 9 groups that 2.
The third pair tells us we could have 3 teams of 6 or 6 groups that 3.
Now we have the right to see the there space three possible combinations for group the party guests: (1,18), (2,9), (3,6).
Example 3: Xin has a plot that land through an area that 18 sq. Ft. He desires to rest this plot of soil into various equal-sized part to plant various vegetables. In just how many can he division the plot?
The area that the rectangle is length × breadth.Given area = 18 square feetSo, the feasible length and also breadth space the variable pairs (as the product of these pairs is 18).
There room 3 possible ways. We can swap the size of length and breadth follow to the situation.
FAQs on determinants of 18
What space the determinants of 18?
The factors of 18 room 1, 2, 3, 6, 9, 18 and its negative factors space -1, -2, -3, -6, -9, -18.
What is the Greatest common Factor of 18 and 13?
The factors of 18 room 1, 2, 3, 6, 9, 18 and the factors of 13 room 1, 13. 18 and 13 have only one usual factor i m sorry is 1. This means that 18 and 13 space co-prime.Hence, the Greatest common Factor (GCF) that 18 and 13 is 1.

What room the usual Factors that 18 and 7?
Since the determinants of 18 are 1, 2, 3, 6, 9, 18, and also factors the 7 room 1, 7. Hence, 18 and also 7 have actually only one common factor i beg your pardon is 1. Therefore, 18 and 7 room co-prime.
What is the amount of the determinants of 18?
All the determinants of 18 room 1, 2, 3, 6, 9, 18 and therefore the amount of all these components is 1 + 2 + 3 + 6 + 9 + 18 = 39
