What are factors?

Answer 1

This normally applies to integers. A factor, or divisor, of an integer is any integer which can be multiplied by another integer, to get the original number.For example, 4 is a factor of 12, since you can multiply 4 x 3, to get 12. The complete list of positive factors of 12 is {1, 2, 3, 4, 6, 12}, since each of these numbers can be multiplied by an integer, to get 12.

Answer 2

A factor is a number or algebraic expression by which another is exactly divisible.

2 is a factor of 4. 2x is a factor of 4x. 2 is not a factor of 5.

Answer 3

They are integers, greater than one, which go into the number evenly.
