Euler theorem example

In number theory, Euler's theorem (also known as the Fermat–Euler theorem or Euler's totient theorem) states that, if n and a are coprime positive integers, and is Euler's totient function, then a raised to the power is congruent to 1 modulo n; that is In 1736, Leonhard Euler published a proof of Fermat's little theorem (stated by Fermat without proof), which is the restriction of Euler's theorem to the case where n is a prime number. Subsequently… WebA corollary of Euler's theorem is: for every positive integer n, if the integer a is coprime with n then for any integers x and y . This follows from Euler's theorem, since, if , then x = y + kφ(n) for some integer k, and one has If …
