# Factor Tree Calculator

Use the calculator below to draw the factors tree of any number if the it is factorable and has less than 15 factors.

## How to draw the factor tree

The procedure below applies to any non-prime number.

- Find 2 factors of the number;
- Look at the 2 factors and determine if at least one of them is not prime;
- If it is not a prime factor it;
- Repeat this process until all factors are prime.

Supose you want to find the factor tree of 32. In this case, you show use the folowing steps:

32 / \ 2 16 / \ 2 8 / \ 2 4 / \ 2 2 |
32 is not prime --> divide by 2
16 is not prime --> divide by 2 8 is not prime --> divide by 2 4 is not prime --> divide by 2 2 is prime --> stop |

Note that these dividers (in this case all are equal to 2) are the prime factors. They are also called the leaves of the factor tree.
