Euler's theorem - Wikipedia
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, then is congruent to modulo n, where denotes Euler's totient function; that is. {\displaystyle a^ {\varphi (n)}\equiv 1 {\pmod {n}}.}

Euler’s Theorem. If \(m\) is a positive integer and \(a\) is an integer such that \((a,m)=1\), then \[a^{\phi(m)}\equiv 1(mod \ m)\]
8.10 Euler’s Theorem The RSA cryptosystem examined in the next section, and other current schemes for encoding secret messages, involve computing remainders of numbers raised to large powers. A basic fact about remainders of powers follows from a theorem due to Euler about congruences. Definition 8.10.1. For n>0, define11

Jun 29, 2023 · Euler's theorem for modular numbers states that for any positive integer \(n\) and any positive integer \(a\) that is coprime to \(n\), the equation \(a^{\phi(n)} \equiv 1 \pmod{n}\) holds true, where \(\phi(n)\) represents Euler's totient function, which gives the count of positive integers less than \(n\) that are coprime to \(n\).
Euler's Theorem - Millersville University of Pennsylvania
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, 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 n which are relatively prime to n.
