WebbIf a (positive) common divisor d divides every linear combination of a and b, then it divides gcd(a,b) (by Bezout's Lemma). This implies d <= gcd(a,b). But gcd(a,b) is the smallest positive integer which can be expressed as a linear combination of a,b. Thus d cannot be written as a linear combination of a,b (unless d = gcd(a,b)). WebbWe prove that for natural numbers a and b, there are integers x and y such that ax+by=gcd(a,b). This is also called Bezout's Identity, although it was known ...
