Extended euclid algorithm

WebThe Euclidean Algorithm gives you a constructive way of finding r and s such that ar + ms = gcd (a, m), but if you manage to find r and s some other way, that will do it too. As soon as you have ar + ms = 1, that means that r is the modular inverse of a modulo m, since the equation immediately yields ar ≡ 1 (mod m). WebThe extended Euclidean algorithm will give us a method for calculating p efficiently (note that in this application we do not care about the value for s, so we will simply ignore it.) …
