Bezout’s Identity Calculator

Bezout’s Identity states that for any two integers a and b, there exist integers x and y such that ax + by = GCD(a, b). It provides a fundamental relationship between the GCD of two integers and their linear combination, enabling solutions to Diophantine equations and applications in number theory and cryptography.

Bezout’s Identity relates the greatest common divisor (GCD) of two integers, a and b, to their linear combinations in the form of ax + by = GCD(a, b), where x and y are integers. Here’s a simple table illustrating Bezout’s Identity for various values of a and b:

In each row of the table, we have two integers, a and b, their GCD(a, b), and the corresponding Bezout’s Identity expressing the GCD as a linear combination of a and b. The values of x and y are chosen in such a way that ax + by equals the GCD(a, b) listed in the table.
