# Bézout coefficients

This online calculator computes Bézout's coefficients for two given integers and represented them in the general form

### This page exists due to the efforts of the following people:

General form

Bézout's identity and Bézout's coefficients

To recap, the Bézout's identity (aka Bézout's lemma) is the following statement:

Let a and b be integers with 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
