Bézout's identity and Bézout's coefficients
To recap, Bézout's identity (aka Bézout's lemma) is the following statement:
Let a and b be integers with the greatest common divisor d. Then, there exist integers x and y such that ax + by = d. More generally, the integers of the form ax + by are exactly the multiples of d.
If d is the greatest common divisor of integers a and b, and x, y is any pair of Bézout's coefficients, the general form of Bézout's coefficients is
and the general form of Bézout's identity is
