Can You Make a factor tree for a prime number?
You can pick any two factors. The end result will be the same no matter which ones you start with. Note that if there are no factors that equal the original number when multiplied together, other than that number and the number “1,” the number is considered a prime number and cannot be made into a factor tree.
What is a number tree?
A special diagram where we find the factors of a number, then the factors of those numbers, etc, until we can’t factor any more. The ends are all the prime factors of the original number. Here we see the factor tree of 48 which reveals that 48 = 2 × 2 × 2 × 2 × 3. See: Prime Factor. Factors and Multiples.
What is the tree method in math?
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.

How do you draw a factor tree?
How to use a factor tree
- Write the number at the top of the factor tree and draw two branches below.
- Fill in the branches with a factor pair of the number above.
- Continue until each branch ends in a prime number.
- Write the solution as a separate line of working (in index form if required)

How do prime factor trees work?
Factor trees It is often useful to write a number as the product of its prime factors. This can be done by listing the factor pairs as successive branches in a factor tree. The branches continue to expand until all the factors are prime numbers.
