gcd(a+k,b+k) code example

Example: gcd in c++

#include<iostream>
using namespace std;

int euclid_gcd(int a, int b) {
	if(a==0 || b==0) return 0;
	int dividend = a;
	int divisor = b;
	while(divisor != 0){
		int remainder = dividend%divisor;
		dividend = divisor;
		divisor = remainder;
	}
	return dividend;
}

int main()
{
	cout<<euclid_gcd(0,7)<<endl;
	cout<<euclid_gcd(55,78)<<endl;
	cout<<euclid_gcd(105,350)<<endl;
	cout<<euclid_gcd(350,105)<<endl;
	return 0;
}
