## Euclidean algorithm - Wikipedia

The Euclidean algorithm is one of the oldest algorithms in common use. It appears in Euclid's Elements (c. 300 BC), specifically in Book 7 (Propositions 1–2) and Book 10 (Propositions 2–3). In Book 7, the algorithm is formulated for integers, whereas in Book 10, it is formulated for lengths of line segments. (In modern usage, one would say it was formulated there for real numbers. But lengths, areas, and volumes, represented as real numbers in modern usage, are not measured in the same units and there is no nat

Understanding the Euclidean Algorithm. If we examine the Euclidean Algorithm we can see that it makes use of the following properties: GCD (A,0) = A. GCD (0,B) = B. If A = B⋅Q + R and B≠0 then GCD (A,B) = GCD (B,R) where Q is an integer, R is an integer between 0 and B-1. The first two properties let us find the GCD if either number is 0.
