Trying the solution aφ(n) ≡ 1 (mod n), we see that it works, and by the Chinese remainder … WebEuler’sTheorem Euler’s theorem generalizes Fermat’s theorem to the case where the modulus is composite. The key point of the proof of Fermat’s theorem was that if p is prime, {1,2,...,p − 1} are relatively prime to p. This suggests that in the general case, it might be useful to look at the numbers less than the modulus
