  2. Definition of Coprime - Mathematics Stack Exchange

    Feb 2, 2018 · In number theory, two integers a a and b b are said to be relatively prime, mutually prime, or coprime (also written co-prime) if the only positive integer (factor) that divides both of them is 1 1. …

  3. Is any number coprime to itself? - Mathematics Stack Exchange

    Dec 21, 2020 · I have a fundamental question, we know that Coprime numbers are integers that have only 1 as their common factor. Now, my question is how it works for the same numbers, for example, …
