A composite factor is a factor that is a composite number, asopposed to a prime factor which is a factor that is a prime number. A factor is a number or quantity that when multiplied with another produces a given number or expression.
Factors are numbers you can multiply together to get another number: Example: 2 and 3 are factors of 6, because 2 Ã 3 = 6. A number can have MANY factors! Example: What are the factors of 12? 3 and 4 are factors of 12, because 3 Ã 4 = 12. Also 2 Ã 6 = 12 so 2 and 6 are also factors of 12. And 1 Ã 12 = 12 so 1 and 12 are factors of 12 as well. So 1, 2, 3, 4, 6 and 12 are all factors of 12 And -1, -2, -3, -4, -6 and -12 also, because multiplying negatives makes a positive. In Algebra, factors are what you can multiply together to get an expression.
