Factor Tree of 84

Given number is 84
The factor tree of 84 is as follows:

	84
2		42
	2		21
		3		7

84 = 2 x 42

42 = 2 x 21

21 = 3 x 7

If we write into multiples it would be 84 x 2

On splitting 42 further and writing it as multiples of numbers it would be 21 x 2.

On splitting 21 further and writing it as multiples of numbers it would be 7 x 3.

Here are examples of Factor tree calculations.

• Factor Tree of 85
• Factor Tree of 86
• Factor Tree of 87
• Factor Tree of 88
• Factor Tree of 89

Here we are providing different methods to find the factors of the number 84. 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 84. Let’s start with 2 x 2 x 3 x 7 as it results in 84 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 84 now and we can write as 2 x 2 x 3 x 7 and place those factors on the tree. similarly to prime numbers obtained in the first step 2, 2, 3, 7 obtained here are also prime numbers and we will end up these branches.
