Beside this, whats is a factor?
Purplemath. "Factors" are the numbers you multiply to get another number. For instance, factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4.
what is a factor of 12? 12 = 1 x 12, 2 x 6, or 3 x 4. Factors of 12: 1, 2, 3, 4, 6, 12. Prime factorization: 12 = 2 x 2 x 3, which can also be written 12 = 2² x 3.
Considering this, what is the factors of 42?
42 is a composite number. 42 = 1 x 42, 2 x 21, 3 x 14, or 6 x 7. Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42. Prime factorization: 42 = 2 x 3 x 7.
What is a factor example?
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.
