To see this, look at these two cases: If b >= a/2 then on the next step you'll have a' = b and b' < a/2 since the % operation will remove b or more from a. If b < a/2 then on the next step you'll have a' = b and b' < a/2 since the % operation can return at most b - 1. check back teamstepps

http://duoduokou.com/algorithm/66083732990536596267.html WebIn mathematics, the Euclidean algorithm, [note 1] or Euclid's algorithm, is an efficient method for computing the greatest common divisor (GCD) of two integers (numbers), the largest number that divides them both without a remainder. It is named after the ancient Greek mathematician Euclid, who first described it in his Elements (c. 300 BC).

Web33. I know that Euclid’s algorithm is the best algorithm for getting the GCD (great common divisor) of a list of positive integers. But in practice you can code this algorithm in various ways. (In my case, I decided to use Java, but C/C++ may be another option). I need to use the most efficient code possible in my program.

WebThe extended Euclidean algorithm is an algorithm to compute integers x x and y y such that ax + by = \gcd (a,b) ax +by = gcd(a,b) given a a and b b. The existence of such integers is guaranteed by Bézout's lemma.
