Euclidean algorithm: A fast algorithm for the greatest common divisor of two integers. That is what is commonly referred to as the "Euclidean method". Given two integers a, b. Euclid can find A, B greatest common divisor in the complexity of log

operational rules for modulesArithmetic RulesThe modulo operation is somewhat similar to the basic arithmetic, but with the exception of division. The rules are as follows: (A + b)% P = (a% p + b% p)% p (1) (A-a)% P = (a% p-b p)% P (2) (A * b)% P = (
