Factor Tree of 40

Given number is 40
The factor tree of 40 is as follows:

	40
2		20
	2		10
		2		5

40 = 2 x 20

20 = 2 x 10

10 = 2 x 5

If we write into multiples it would be 40 x 2

On splitting 20 further and writing it as multiples of numbers it would be 10 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 41
• Factor Tree of 42
• Factor Tree of 43
• Factor Tree of 44
• Factor Tree of 45

Here we are providing different methods to find the factors of the number 40. 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 40. Let’s start with 2 x 2 x 2 x 5 as it results in 40 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 40 now and we can write as 2 x 2 x 2 x 5 and place those factors on the tree. similarly to prime numbers obtained in the first step 2, 2, 2, 5 obtained here are also prime numbers and we will end up these branches.
