"WebbThis is the same line of reasoning applied to the proof of Fermat's theorem. As is the case for Fermat's theorem, an alternative form of the theorem is also useful: Equation 8-5 . Again, similar to the case with Fermat's theorem, the first form of Euler's theorem [Equation (8.4)] requires that a be relatively prime to n, but this form does not. " - Stallings theorem
