How is multiple and factor different?

Answer 1

The only number that is both a multiple of a number and a factor of that same number is the number itself.

Multiples of a number are equal to or bigger than the number, while factors are equal to or smaller than the number.

Answer 2

They have an inverse relationship in the sense that if A is a multiple of B, then B is a factor of A.

Answer 3

Factors go into numbers, numbers go into multiples.
