Fast Modulo Multiplicative Inverse Calculator Online

A computational tool determines the multiplicative inverse of an integer, given a modulus. Specifically, for integers ‘a’ and ‘m’, the calculator finds an integer ‘x’ such that the product of ‘a’ and ‘x’ is congruent to 1 modulo ‘m’. In simpler terms, (a x) mod m = 1. For instance, if a = 3 and m = 11, the multiplicative inverse is 4, because (3 4) mod 11 = 12 mod 11 = 1. This inverse exists only if ‘a’ and ‘m’ are coprime (their greatest common divisor is 1).
