Multiplicative inverse of 19 modulo 21

Web13 apr. 2024 · Taking modulo 141, we get 104/2 = 52. This can also be solved in the following manner: Let x = 1/19 (mod 141). So, 19x = 141y + 1. This can be written as 19x … WebVariants of the definition In mathematics, the result of the modulo operation is an equivalence class, and any member of the class may be chosen as representative ; however, the usual representative is the least positive residue, the smallest non-negative integer that belongs to that class (i.e., the remainder of the Euclidean division). However, …
