What are factors and multiples

① If an integer can be divided by another integer, this integer is a multiple of another integer. For example, 15 can be divided by 3 or 5, so 15 is a multiple of 3 and also a multiple of 5. ② the quotient of a number divided by another number. For example, a △ B = C, that is to say, a is a multiple of B, and a is a multiple of B. If a number can divide its product, then this number is a factor, The product of a number is a multiple. 3 × 5 = 15 ↑ ↑ factor 1 factor 2 multiple. For example: a △ B = C, we can say that a is a C multiple of B. ③ there are countless multiples of a number, that is to say, the set of multiples of a number is an infinite set. Note: a number can not be called a multiple alone, only whose multiple is
