If two counting numbers a and b multiply to give m, what are a and b called?

1. When two counting numbers multiply together to give a product, each of those numbers is called a factor of that product. 2. The example of 8 and 9 multiplying to 72 shows that 8 and 9 are described as factors of 72. 3. Multiples run in the opposite direction, since 72 is a multiple of 8 and of 9, not the other way around. _Source: OpenStax Prealgebra (CC BY 4.0), Ch 2 "The Language of Algebra", section 2.4 Find Multiples and Factors_
