Question

State the Euler's theorem ​

Answer 1

In number theory, Euler's theorem states that if n and a are coprime positive integers, then where is Euler's totient function. In 1736, Leonhard Euler published his proof of Fermat's little theorem, which Fermat had presented without proof. 

Answer 2

In general, Euler's theorem states that, “if p and q are relatively prime, then ”, where φ is Euler's totient function for integers. That is, is the number of non-negative numbers that are less than q and relatively prime to q. Proof of Euler's theorem: ... These elements are relatively (co-prime) to q.
