The factor tree method is quite flexible – at each branch you can break the number into any factors until you reach the prime factors. The result is the same: 36 = 3 × 2 × 2 × 3 Although the order of the factors may be different because we can start with different pairs of factors, every factor tree of 36 has the same prime factorization.

Factor Trees. One method for producing the prime factorization of a natural number is to use what is called a factor tree. The first step in making a factor tree is to find a pair of factors whose product is the number that we are factoring. These two factors are the first branching in the factor tree.

The Factor Trees Gizmo has two modes. In Factor mode, you can create factor trees to factor composite numbers into primes. In Build mode, you can build numbers by multiplying primes together. Can you build all composite numbers up to 50? Any whole composite number up to 999 can be factored or built with the Gizmo.
