What's a factor in math?

factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. … The prime factors of a number or an algebraic expression are those factors which are prime.

What is 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.
