what greatest common divisor

1. Euclidean algorithm (recursive ball two number of greatest common divisor)The algorithm is simple to paste the code directly:int gcd (int a, int b) {Return b ==0? A:GCD (b, a%b);}On the basis of this algorithm can be entered, gcd (A*n, B*n)

Usually equipped with special effects. Do not pursue too harsh attributes, use the following method 10 million or so can be out of special effects.1-3 stars in the sectarian central China, 4-5 stars in the identification of old cattle, 6-8 stars by

Greatest common divisor Euclidean algorithmDescription: Calculates the greatest common divisor of two non-negative integers p and Q: If q is 0, then greatest common divisor is p. Otherwise, p is divided by Q to get the remainder r,p and

Euclidean algorithm, also known as the greatest common divisor method, is used to calculate two integers, a, b, and so on.Basic algorithm: Set A=qb+r, where a,b,q,r are integers, then gcd (A, B) =gcd (b,r), gcd (A, B) =gcd (b,a%b).The first kind of

1. The method of Euclidean algorithmThe greatest common divisor of two integers is obtained by using the method of dividing the two. Note GCD (A, A, b) is a greatest common divisor of two numbers a and a. The theoretical basis for the Euclidean

Identifier naming: Identifiers can consist of letters, numbers, glide lines, and dollar signs, but cannot start with numbers, letters in each identifier are case-sensitive, identifiers are not limited in length, and, finally, identifiers must be
