how to do euclidean algorithm - EAS
- The Euclidean Algorithm for finding GCD (A,B) is as follows: If A = 0 then GCD (A,B)=B, since the GCD (0,B)=B, and we can stop. If B = 0 then GCD (A,B)=A, since the GCD (A,0)=A, and we can stop. Write A in quotient remainder form (A = B⋅Q + R) Find GCD (B,R) using the Euclidean Algorithm since GCD (A,B) = GCD (B,R)

The Euclidean Algorithm (article) | Khan Academy
https://www.khanacademy.org/computing/computer...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.

Euclidean algorithm
https://sites.math.rutgers.edu/~greenfie/gs2004/euclid.html13/07/2004 · The Euclidean algorithm is a way to find the greatest common divisor of two positive integers, a and b. First let me show the computations for a=210 and b=45. Divide 210 by 45, and get the result 4 with remainder 30, so 210=4 · 45+30. Divide 45 by 30, and get the result 1 with remainder 15, so 45=1 · 30+15. Divide 30 by 15, and get the result 2 ...
