Factor Tree of 20

Given number is 20
The factor tree of 20 is as follows:

	20
2		10
	2		5

20 = 2 x 10

10 = 2 x 5

If we write into multiples it would be 20 x 2

On splitting 10 further and writing it as multiples of numbers it would be 5 x 2.

Here are examples of Factor tree calculations.

• Factor Tree of 21
• Factor Tree of 22
• Factor Tree of 23
• Factor Tree of 24
• Factor Tree of 25

Here we are providing different methods to find the factors of the number 20. 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 20. Let’s start with 2 x 2 x 5 as it results in 20 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 20 now and we can write as 2 x 2 x 5 and place those factors on the tree. similarly to prime numbers obtained in the first step 2, 2, 5 obtained here are also prime numbers and we will end up these branches.
