WebJun 17, 2024 · The grouping rule in modular arithmetic is pretty simple: given a number m, we will say that a≡b (mod m) if a−b is an integer multiple of m, i.e a-b=km; where k is an integer. Let’s say m=3, if... WebHow to find a modular inverse. A naive method of finding a modular inverse for A (mod C) is: step 1. Calculate A * B mod C for B values 0 through C-1. step 2. The modular inverse of A mod C is the B value that makes A * B mod C = 1. Note that the term B mod C can only have an integer value 0 through C-1, so testing larger values for B is redundant. the o circuit
