WebThe Euclidean Algorithm makes use of these properties by rapidly reducing the problem into easier and easier problems, using the third property, until it is easily solved by using one of the first two properties. WebFeb 22, 2024 · The Extended Euclidean Algorithm is an algorithm that finds integers x and y such that ax + by = gcd(a,b). The Extended Euclidean Algorithm works in two steps. First, we need to find the GCD. So we use the Euclidean Algorithm to calculate the GCD of two integers. Then, to get x and y, we work backwards recursively.
