👉 In algebra, the term "coprimality" refers to two numbers being relatively prime or having no common factors other than 1. In other words, if a and b are coprime (or relatively prime), then they have no common factors greater than 1 apart from 1. For example, in the set of integers {2, 3, 5}, the numbers 3 and 5 are coprime because their greatest common divisor (gcd) is 1.
