The Euclidean Algorithm is a time-honored technique for determining the greatest common divisor (GCD) of two integers, a crucial element in number theory. This algorithm is not only fundamental for mathematical computations but also plays a significant role in modern cryptography. The Extended Euclidean Algorithm further builds on this by providing coefficients for Bézout's identity, aiding in the calculation of modular inverses, which are essential in encryption methods like RSA.
