You can find prime factors by using a factor tree. A factor tree looks like this. You can also make the tree as shown in the next tree. In either case, no matter how 18 is factored, the product of the primes is the same, even though the order may be different. Example 5. Use a factor tree to express 60 as a product of prime factors. So the ...


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.

A factor tree is a great way to teach students how to find the prime factors of a number given. This worksheet is a visual of a real tree with the factors shown as an example. There are four practice problems included.


The factor tree only grows on one branch if you always begin with a prime factor for each factor pair Factor trees’ branches stop growing when they get to a prime number Students may stop early in their finding of the prime factorization, not realizing that factors of a number can


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.
