WebDoes some standard Python module contain a function to compute modular multiplicative inverse of a number, i.e. a number y = invmod(x, p) such that x*y == 1 (mod p)? Google doesn't seem to give any good hints on this. Of course, one can come up with home-brewed 10-liner of extended Euclidean algorithm, but why reinvent the wheel.

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.
