Applications of Fermat's Little Theorem and Congruences Definition: Let m be a positive integer. Then integers a and b are congruent modulo m, denoted by a = b mod m, if m (a — b). Example: 1 mod 2, Properties: 6 = 4 mod 2, —14 = 0 mod 7, 25 = 16 mod 9, 43 —27 mod 35.

Fermat’s Little Theorem-Robinson 2 Part I. Background and History of Fermat’s Little Theorem Fermat’s Little Theorem is stated as follows: If p is a prime number and a is any other natural number not divisible by p, then the number is divisible by p. However, some people state Fermat’s Little Theorem as,

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, …

02.11.2016 · Apply Fermat's Little Theorem. Show activity on this post. ∑ n = 0 N 10 n = 1 − 10 N + 1 1 − 10 = 10 N + 1 − 1 9. Since p = 2003 is prime, then 9 is invertible mod p, so it suffices to find N such that 10 N + 1 − 1 ≡ 0 ( mod 2003). By Fermat's little theorem, a p − 1 ≡ 1 ( mod p) for any a with gcd ( a, p) = 1.

Proof using group theory ... To prove Fermat's little theorem using group theory, recognize that the set G = {1, 2, …, p − 1} with the operation ...

04.12.2017 · 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 a p ≡ a (mod p).. Special Case: If a is not divisible by p, Fermat’s little theorem is equivalent to the statement that a p-1-1 is an integer multiple of p. a p-1 ≡ 1 (mod p) OR a p-1 % p = 1

If p is a prime, either p|a or (p,a)=1. If p|a,p will divide an−a=a(an−1−1) for integer n−1≥0. For (p,a)=1,ap−1−1≡0(modp) by Fermat's Little Theorem.

For example, if a = 2 and p = 7, then 27 = 128, and 128 − 2 = 126 = 7 × 18 is an integer multiple of 7. If a is not divisible by p, Fermat's little theorem ...

Find the remainder when you divide 3^100,000 by 53. Since, 53 is prime number we can apply fermat little theorem here. Therefore: 3^53-1 ≡ 1 ( ...
