Best Answer

Zero has an infinite number of factors.

Explanation

Think of a factor as a number that divides another number exactly, that is to say with no remainder. So 2 is a factor of 6 because 6 divided by 2 is 3 exactly. Take an integer n, and we way m is a factor of n if and only if m multiplied by some other integer k equals n. We call k and m a factor pair. For example, 4X1 and 2X2 are the factor pairs of 4. Now consider 0 and observe that any m can be multiplied by 0 to get 0 so there is an infinite number of factors. Every real number can be part of a factor pair with 0. So there are infinite factors and infinite factor pairs.
