Here you can find the answer to questions related to: Factor tree for 1 or how to draw the factor tree for 1.

## Factor Tree Calculator

 Enter a natural number to get its fator tree: Ex.: 6, 9, 26, 256, etc. This calculator accepts big numbers up to 100,000 or more. Results: The number 1 is 1 is not a prime number, but, obviously, we can't draw a tree of just one leaf. No factor tree for 1. It is not possible to draw trees for prime numbers.

## 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.
