Euler’s and Fermat’s theorem The Euler’s theorem is very useful in the number theory: Theorem 1. If $a$ and $m$ are relatively prime numbers, then a φ ( m) ≡ 1 ( mod m). Proof. Let $m$ be a natural number and let s 1, s 2, …, s r, r = φ ( m), be a reduced residue system modulo $m$. Then a s 1, a s 2, …, a s r

EULER'S AND FERMAT THEOREM and C which will show that the number of elements in A × B is equal to the number of elements in C. This will be done by showing that to each element (a i,b j) in A × B, there exists a unique c k in C and that to each c k in C there exists an element (a i,b j) in A × B. Moreover, we shall show that if we start with (a i, b j

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

Then we have the following result, which is usually referred to as the Euler- Fermat Theorem: it is due to Euler, but contains Fermat’s Little Theorem as a special case. Theorem 7.1. If ais an integer coprime to m≥ 2, then aϕ(m)≡ 1 mod m. For m= pprime, we have φ(p) = p− 1, and Euler’s Theorem becomes Fermat’s Little Theorem. Proof. Let [r

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 Fermatwithout proof), which is the restriction of Euler's theorem to the case where n is a prime number. Subsequently, …

Euler’s theorem Theorem (20.8, Euler’s theorem) Let n be a positive integer. Then for all integers a relatively prime to n, we have aφ(n) ≡ 1 mod n. Proof. Similar to the proof of Fermat’s theorem. (Apply the Lagrange theorem to the group Z× n.) Example Let us compute 499 mod 35. We have 4φ(35) ≡ 1 mod 35, i.e., 424 ≡ 1 mod 35.

Fermat's theorem. Theorem (20.1, Little theorem of Fermat). Let p be a prime. Then for all integers a not divisible by p, we have ap−1 ≡ 1 mod p.

Euler's theorem is a generalization of Fermat's little theorem dealing with powers of integers modulo positive integers. It arises in applications of elementary number theory, including the theoretical underpinning for the RSA cryptosystem. Let n n n be a positive integer, and let a a a be an integer that is relatively prime to n. n. n. Then
