t k = t k−2 − q k t k−1. with the starting values s −2 = 1, t −2 = 0 s −1 = 0, t −1 = 1. Using this recursion, Bézout's integers s and t are given by s = s N and t = t N, where N+1 is the step on which the algorithm terminates with r N+1 = 0. The validity of this approach can be shown by induction.
The greatest common divisor (GCD) of integers a and b, at least one of which is nonzero, is the greatest positive integer d such that d is a divisor of both a and b; that is, there are integers e and f such that a = de and b = df, and d is the largest such integer.
Therefore, equalities like d = gcd(p, q) or gcd(p, q) = gcd(r, s) are common abuses of notation which should be read "d is a GCD of p and q" and "p and q have the same set of GCDs as r and s". In particular, gcd( p , q ) = 1 means that the invertible constants are the only common divisors.
