A modular multiplicative inverse of an integer a with respect to the modulus m is a solution of the linear congruence. The previous result says that a solution exists if and only if gcd (a, m) = 1, that is, a and m must be relatively prime (i.e. coprime).

What is a modular inverse? In modular arithmetic we do not have a division operation. However, we do have modular inverses. The modular inverse of A (mod C) is A^-1. (A * A^-1) ≡ 1 (mod C) or equivalently (A * A^-1) mod C = 1. Only the numbers coprime to C (numbers that share no prime factors with C) have a modular inverse (mod C)

4 dni temu · A modular inverse of an integer b (modulo m) is the integer b^(-1) such that bb^(-1)=1 (mod m). A modular inverse can be computed in the Wolfram Language using PowerMod[b, -1, m]. Every nonzero integer b has an inverse (modulo p) for p a prime and b not a multiple of p.
