The greatest common divisor c, of a and b, denoted as c = gcd(a,b), is the largest number that divides both a and b. One way to write c is as a linear combination of a and b. Then c is the smallest natural number such that c = ax + by or x, y e Z. We say that a and b are relatively prime iff gcd(a, b) = 1. %3D Prove: Va e Z, Vb e Z, Vc e Z, ac =, bc ^ gcd(c,n) = 1 → a =n b.
