For example, 2X6= 12, and the product of 2 and 6 is 12, so 2 and 6 are factors of 12. 12 is a multiple of 2 and also a multiple of 6.

3X(-9)=-27, 3 and -9 are all factors of -27. -27 is a multiple of 3 and -9.

Generally speaking, the integer A is multiplied by the integer B to get the integer C. Both the integer A and the integer B are called factors of the integer C. Conversely, the integer C is a multiple of the integer A and also a multiple of the integer B. ..

Extended data:

Factor or divisor is a mathematical term. Definition: The quotient (b≠0) of an integer A divided by an integer B is exactly an integer with no remainder, so we say that B is a factor of A .. 0 is not a factor of 0.

Definition of primary school mathematics: If a*b=c(a, B and C are all integers), then we call A and B factors of C. It should be noted that this relationship only holds if the dividend, divisor and quotient are integers and the remainder is zero. Conversely, we call C a multiple of A and B. When learning factors and multiples, primary school mathematics does not consider 0.
