Some of the more advanced properties of congruence relations are the following: • Fermat's little theorem: If p is prime and does not divide a, then a ≡ 1 (mod p). • Euler's theorem: If a and n are coprime, then a ≡ 1 (mod n), where φ is Euler's totient function • A simple consequence of Fermat's little theorem is that if p is prime, then a ≡ a (mod p) is the multiplicative inverse of 0 < a < p. More generally, from Euler's theorem, if a and n are coprime, then a ≡ a (mod n).

WebEuler 's Theorem states that if gcd ( a, n) = 1, then aφ (n) ≡ 1 ( mod n ). Here φ ( n) is Euler's totient function: the number of integers in {1, 2, . . ., n -1} which are relatively prime to n. When n is a prime, this theorem is just Fermat's little theorem. For example, φ (12)=4, so if gcd ( a ,12) = 1, then a4 ≡ 1 (mod 12).
