What is the factor tree?
Factor trees are a way of expressing the factors of a number, specifically the prime factorization of a number. Each branch in the tree is split into factors. Once the factor at the end of the branch is a prime number, the only two factors are itself and one so the branch stops and we circle the number.

What does a factor tree give us?
What the tree does give us is a number’s prime factorization. A number’s prime factorization is simply the list of prime numbers you would multiply together to get a certain product. On a factor tree, all the prime numbers at the ends of branches give us the prime factors.
How to draw the factor tree of a number?
How to draw the factor tree 1 Find 2 factors of the number; 2 Look at the 2 factors and determine if at least one of them is not prime; 3 If it is not a prime factor it; 4 Repeat this process until all factors are prime.
What is the prime factorization of 100 using factor trees?
So 100’s prime factorization is 2 * 2 * 5 * 5, or 2^2 * 5^2. Every number has one unique prime factorization, just like every person has one unique fingerprint. Unlike a family tree, which is fixed and can only occur in one way, some factor trees have different possible arrangements.
