Web1 day ago · The modular inverse of a mod m exists only if a and m are relatively prime i.e. gcd (a, m) = 1. Hence, for finding the inverse of an under modulo m, if (a x b) mod m = 1 then b is the modular inverse of a. Example: a = 5, m = 7 (5 x 3) % 7 = 1 hence, 3 is modulo inverse of 5 under 7.
