WebJul 12, 2013 · For example, find the multiplicative inverse of 2, mod 7. [G,D] = gcd(2,7) G = 1. D =-3. The second argument will be a multiplicative inverse of 2, as long as G is 1. G is the GCD of the two numbers, and if they are relatively prime, then G will be 1. If so, then D will be a multiplicative inverse.

How to find Multiplicative Inverse of a number modulo M?
WebIn ordinary arithmetic, the multiplicative inverse of b is the reciprocal of b, namely 1/b. For example, let's say we are working with a modulus of 7. The multiplicative inverse of 3 is 5 because 3 times 5 is 1. (For the same reason, the multiplicative inverse of 5 is 3.) We can find multiplicative inverses by building a multiplication table. WebSection 4.2 : The Inverse of a Matrix If we divide a real number by 5 we are multiplying it by 1 5: 1 5 is the reciprocal or multiplicative inverse of 5 in R. This means 1 5 × 5 = 1, i.e., if you multiply 5 by 1 5, you get 1; multiplying by 1 5 “reverses” the work of multiplying by 5. Which n × n matrices have multiplicative inverses?
