WebMar 9, 2013 · To provide a concise and clear explanation to the proof of Fermat's Last Theorem would essentially require an elementary proof. An elementary proof is a proof that only uses basic … WebIn 1640 he stated what is known as Fermat’s little theorem —namely, that if p is prime and a is any whole number, then p divides evenly into ap − a. Thus, if p = 7 and a = 12, the far-from-obvious conclusion is that 7 is a divisor of 12 7 − 12 = 35,831,796. This theorem is one of the great tools of modern number theory.
WebJul 24, 2024 · Fermat’s little theorem would become the basis for the Fermat primality test, a probabilistic method of determining whether a number is a probable prime. If we for instance want to find out whether n = 19 is prime, randomly pick 1 < a < 19, say a = 2. Calculate n − 1 = 18, and its factors: 9, 6. We check by calculating 2¹⁸ ≡ 1 (mod 19 ...

Fermat's little theorem is the basis for the Fermat primality test and is one of the fundamental results of elementary number theory. The theorem is named after Pierre de Fermat, who stated it in 1640. It is called the "little theorem" to distinguish it from Fermat's Last Theorem. See more Fermat's little theorem states that if p is a prime number, then for any integer a, the number $${\displaystyle a^{p}-a}$$ is an integer multiple of p. In the notation of modular arithmetic, this is expressed as See more Pierre de Fermat first stated the theorem in a letter dated October 18, 1640, to his friend and confidant Frénicle de Bessy. His formulation is equivalent to the following: If p is a prime and a is any integer not divisible by p, then a − 1 is divisible by p. Fermat's original … See more The converse of Fermat's little theorem is not generally true, as it fails for Carmichael numbers. However, a slightly stronger form of the theorem is true, and it is known as Lehmer's … See more The Miller–Rabin primality test uses the following extension of Fermat's little theorem: If p is an odd prime and p − 1 = 2 d with s > 0 and d odd > 0, then for every a coprime to p, either a ≡ 1 (mod p) or there exists r such that 0 … See more Several proofs of Fermat's little theorem are known. It is frequently proved as a corollary of Euler's theorem. See more Euler's theorem is a generalization of Fermat's little theorem: for any modulus n and any integer a coprime to n, one has $${\displaystyle a^{\varphi (n)}\equiv 1{\pmod {n}},}$$ where φ(n) denotes Euler's totient function (which counts the … See more If a and p are coprime numbers such that a − 1 is divisible by p, then p need not be prime.
