Fermat's little theorem (not to be confused with Fermat's last theorem) states that if p is a prime number, then for any integer a, This means that if you take some number a, multiply it by itself p times and subtract a, the result is divisible by p (see modular arithmetic).

Fermat’s Little Theorem may be used to calculate efficiently, modulo a prime, powers of an integer not divisible by the prime. Example 1. Calculate 2345 mod11 efficiently using Fermat’s Little Theorem. Solution. The number 2 is not divisible by the prime 11, so 210 ≡ 1 (mod 11)

Since there are only m possible remainders, some two of these m + 1 numbers must have the same remainder on division by m. Thus there exists r, s with 0 ≤ r<s ...

Fermat’s Little Theorem is a special case of Euler’s Theorem because, for a prime p, Euler’s phi function takes the value φ(p) = p−1. Note that, for a prime p, saying that an integer a is relatively prime to p is equivalent to saying that p does not divide a. Euler’s Corollary is also a special case of Euler’s Theorem because, for ...
