Extended information:

If a*b=c (a, b, c are all integers) , then we say a and b are factors of c. It should be noted that this relationship is only true when the dividend, divisor, and quotient are all integers and the remainder is zero. Conversely, we call c a multiple of a and b. When studying factors and multiples, zero is not considered.

In primary school mathematics, when two positive integers are multiplied, both numbers are called factors of the product, or divisors.

In fact, factors are generally defined on integers: let A be an integer and B be a non-zero integer. If there is an integer Q such that A=QB, then B is said to be a factor of A, denoted as B|A . However, some authors do not require B≠0.
