辗转相除法, 又名欧几里德算法(Euclidean algorithm)乃求两个正整数之最大公因子的算法。 算法示意图 递归法 int getGcd(int a, int b) { return b == 0 ? a : getGcd(b, a % b); } 示例代码 #include <stdio.h> #include <math.h> int getGcd(int a, int b) { return b == 0 ? a...
通常的生产代码中使用的最大公约数算法是一种称作binary GCD的算法,其算法描述如下, openssl中使用的BN_gcd便使用了该算法
Euclidean algorithm, procedure for finding the greatest common divisor (GCD) of two numbers, described by the Greek mathematician Euclid in his Elements (c. 300 bc). The method is computationally efficient and, with minor modifications, is still used by
不知道怎么证明N/gcd(N,M),从直观上其实比较好理解。。 //you can also use includes, for example://#include <algorithm>intgcd (inta,intb) {if(a<b) {returngcd(b,a); }if(a%b==0) {returnb; }returngcd(b,a%b); }intsolution(intN,intM) {//write your code in C++98returnN/gcd...

Euclid's gcd algorithmThe function LM , which arises in the pinwheel scheduling problem, was previously known to be computable in polynomial time. In this paper we present a practical algorithm to compute LM that runs in linear time.doi:10.1007/BF02523234T. H. Romer...

While the Euclidean algorithm calculates only the greatest common divisor (GCD) of two integers a and b , the extended version also finds a way to represent GCD in terms of a and b , i.e. coefficients x and y for which:...
