Extended Euclidean Algorithm - UC Denver

We were forced to do arithmetic modulo 26, and sometimes we had to find the inverse of a number mod 26. This turned out to be a difficult task (and not always possible). We observed that a number x had an inverse mod 26 (i.e., a number y so that xy = 1 mod 26) if and only if gcd(x, 26) = 1.

Euler's theorem - Wikipedia

1. Euler's theorem can be proven using concepts from the theory of groups: The residue classes (mod n) that are coprime to n form a group under multiplication (see the article Multiplicative group of integers modulo n for details). The order of that group is (). where . denotes Euler's totient function.
