Factor Tree of 18

A factor tree is a type of diagram in which we find the factors of a number and then the factors of those numbers until we can no longer factor them. We can get the factor tree of 18 easily by putting the number 18 in the input box of the Factor Tree Calculator.

Check the different methods to find the factor tree of 18 in the following sections

Factors of 18

18 = 2 x 9

9 = 3 x 3

If we write into multiples it would be 18 x 2

On splitting 9 further and writing it as multiples of numbers it would be 3 x 3.

Altogether expressing the number in terms of prime factors would be 2 x 3 x 3.

Ways to Find Factors of 18

Here we are providing different methods to find the factors of the number 18. They are splitting numbers and prime factors.

Splitting Numbers

We can divide the number into either of its two factors. In other words, we are looking for the numbers that when multiplied together eqaul 18. Let’s start with 2 x 3 x 3 as it results in 18 on multiplying. We will now find the factors or ancestors of split factors, just like in any family tree.

Prime Factors

Let’s take a look at 18 now and we can write as 2 x 3 x 3 and place those factors on the tree. similarly to prime numbers obtained in the first step 2, 3, 3 obtained here are also prime numbers and we will end up these branches.
