Fermat's little theorem is a fundamental theorem in elementary number theory, which helps compute powers of integers modulo prime numbers. It is a special case of Euler's theorem, and is important in applications of elementary number theory, including primality testing and public-key cryptography.

Proof of Fermat's Little Theorem Fermat's "biggest", and also his "last" theorem states that xn + yn = zn has no solutions in positive integers x, y, z with n > 2. This has finally been proven by Wiles in 1995. Here we are concerned with his "little" but perhaps his most used theorem which he stated in a letter to Fre'nicle on 18 October 1640:

Apr 20, 2021 · Fermat’s little theorem states that if p is a prime number, then for any integer a, the number a p – a is an integer multiple of p. Here p is a prime number ap ≡ a (mod p). Attention reader! Don’t stop learning now.

Fermat's Little Theorem was first stated, without proof, by Pierre de Fermat in 1640. Chinese mathematicians were aware of the result for ...

Fermat's little theorem is a fundamental theorem in elementary number theory, which helps compute powers of integers modulo prime numbers.

Fermat's Little Theorem is highly useful in number theory for simplifying the computation of exponents in modular arithmetic (which ...

Some of the proofs of Fermat's little theorem given below depend on two simplifications. The first is that we may assume that a is in the range 0 ≤ a ≤ p − 1. This is a simple consequence of the laws of modular arithmetic; we are simply saying that we may first reduce a modulo p. This is consistent with reducing modulo p, as one can check.

20.05.2020 · Fermat’s Little Theorem is a beautiful number-theoretic result which states that, for any integer a and any prime number p, aᵖ﹣a is divisible by p.For example, if a = 4 and p = 3 then aᵖ﹣a = 60 which is divisible by 3.. Fermat first proposed this in a 1640 letter to a friend, but stated that he would not show a proof because it would take up too much space in the letter.

This proof, discovered by James Ivory and rediscovered by Dirichlet requires some background in modular arithmetic. Let us assume that p is positive and not divisible by a. The idea is that if we write down the sequence of numbers (A)

And Fermat's little theorem follows from this congruence by canceling a which is allowed if p does not divide a. The proof uses the binomial theorem.
