PHI Function - Formula, Examples, How to Use PHI Function

Phi is a multiplicative function [ edit] This means that if gcd (m, n) = 1, then φ(m) φ(n) = φ(mn). Proof outline: Let A, B, C be the sets of positive integers which are coprime to and less than m, n, mn, respectively, so that A = φ(m), etc. Then there is a bijection between A × B and C by the Chinese remainder theorem .
