How do you find a multiplicative inverse in modulo …

Web(That's really the same idea: -4 is the inverse of 4 because -4 + 4 = 0.) For example, because 2+3=0 mod 5, 3 is the additive inverse of 2 (and vice versa). This means that (x-2) mod 5 and (x+3) mod 5 are going to always be the same. Now, about division. The analog for an additive inverse is the multiplicative inverse.

WebA modular multiplicative inverse of a modulo m can be found by using the extended Euclidean algorithm. The Euclidean algorithm determines the greatest common divisor (gcd) of two integers, say a and m. If a has a multiplicative inverse modulo m, this gcd must be 1. The last of several equations produced by the algorithm may be solved for this gcd.
