Fermat’s last theorem Definition, Example, & Facts Britannica
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. Visa mer 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 Visa mer 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 … Visa mer 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 … Visa mer 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 … Visa mer Several proofs of Fermat's little theorem are known. It is frequently proved as a corollary of Euler's theorem. Visa mer Euler's theorem is a generalization of Fermat's little theorem: for any modulus n and any integer a coprime to n, one has Visa mer If a and p are coprime numbers such that a − 1 is divisible by p, then p need not be prime.
