What is the coprime of 100?

A coprime (or relatively prime) number with respect to 100 is any number that shares no common factors with 100 other than 1. For example, numbers like 3, 7, and 99 are coprime to 100 because they do not divide evenly into 100. In general, any number that is not a multiple of 2 or 5 (the prime factors of 100) would be coprime to it.
