WebApplications. One of the applications of the Extended Euclidean Algorithm is to calculate the multiplicative inverse of a number. We know that the algorithm gives the GCD of two numbers plus numbers x and y that satisfy the equation ax + by = gcd (a,b). If gcd (a,b)=1, then y is the multiplicative inverse of b mod a. This means that b*y mod a =1.
