how to find hcf in c++
// C++ program to find GCD of two numbers
#include <iostream>
using namespace std;
// Recursive function to return gcd of a and b
int gcd(int a, int b)
{
if (b == 0)
return a;
return gcd(b, a % b);
}
// Driver program to test above function
int main()
{
int a = 98, b = 56;
cout<<"GCD of "<<a<<" and "<<b<<" is "<<gcd(a, b);
return 0;
}
