### Factor Tree of 81 to Calculate the Factors

 81 3 27 3 9 3 3 81 = 3 x 27

27 = 3 x 9

9 = 3 x 3

If we write into multiples it would be 81 x 3

On splitting 27 further and writing it as multiples of numbers it would be 9 x 3.

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 3 x 3 x 3 x 3.

### Ways to Find Factors of 81

Here we are providing different methods to find the factors of the number 81. 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 81. Let’s start with 3 x 3 x 3 x 3 as it results in 81 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 81 now and we can write as 3 x 3 x 3 x 3 and place those factors on the tree. similarly to prime numbers obtained in the first step 3, 3, 3, 3 obtained here are also prime numbers and we will end up these branches.
