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...
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

To determine if two numbers are relatively prime, you can find their GCD using the Euclidean algorithm. If the GCD is 1, then the numbers are relatively prime. If the GCD is greater than 1, then the numbers are not relatively prime. Can any two numbers be relatively pri...
