Web(b) At each step, if the old numbers are linear combinations of mand n, then so are the new numbers. (c) By (a) and (b), the last two numbers in the algorithm must be linear combinations of mand n. (d) The last two numbers in the algorithm are (m,n) and 0. Therefore, (m,n) is a linear combination of m Webnative method to compute the gcd of two given positive integers a,b. The method provides at the same time a solution to the Diophantine equation: ax+by = gcd(a,b). It is based on the following fact: given two integers a ≥ 0 and b > 0, and r = a mod b, then gcd(a,b) = gcd(b,r).
