WebSep 11, 2016 · The multiplicative inverse or simply the inverse of a number n, denoted n^ (−1), in integer modulo base b, is a number that when multiplied by n is congruent to 1; that is, n × n^ (−1) ≡ 1 (mod b). For example, 5^ (−1) integer modulo 7 is 3 since (5 × 3) mod 7 = 15 mod 7 ≡ 1. The number 0 has no inverse. Not every number is invertible. WebMay 10, 2015 · To find the inverse of 7, (mod 11), you must find a solution to 7x ≡ 1 (mod11). (Then x satisfies the definition of inverse.) As suggested in other answers, one way to do this is with the extended Euclidean algorithm, and in fact this is the best general purpose algorithm for this type of problem.
