Abstract
We describe the Euclidean Algorithm, a way of expressing the greatest common divisor of two natural numbers as a “linear combination” of the numbers. This algorithm has a number of important applications, including forming the basis for a different proof of the Fundamental Theorem of Arithmetic. It is also an important ingredient in the RSA procedure for sending secret messages. We also present a proof of Euler’s generalization of Fermat’s Theorem.
