Computations and programming when combined make a very deadly combination. As the ability to solve complex mathematical questions in itself is a great deal. But when one has to do the same thing by writing up a code, things get somewhat more complicated. Not to mention the language your coding in also determines whether it's going to be easy to difficult. So today we're going to write a program to print GCD of Two Integers in C++.

 

What's The Approach? 

 

  • Let us consider a and b to be the two Integers to find GCD of.

 

  • Firstly we'll find the gcd of these two numbers, i.e, using a condition where if a becomes zero we'll return b

 

  • However, if that's not the case then we'll simply recursively return b % a, that way we'll get a gcd as output.

C++ Program To Print GCD of Two Integers

 

Input:

 

a = 98, b = 56

 

Output:

 

GCD of 98 and 56 is 14

 

// 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;  }
