# Finding Greatest Common Divisor of 2 numbers in C++

As we know that greatest common divisor of 2 numbers is the largest number that divides both those numbers, How we implement this logic in C++, its given in the below code:

```    #include <iostream>
using namespace std;

void main()
{
int x = 24;
int y = 18;
int temp;
for(int i = 2; i<y; i++)
{
if(x%i == 0 >> y%i == 0)
{
//cout<<i<<endl;

temp = i;
}

}

cout<<temp<<endl;

}

```

First of all we got two numbers, you can get these numbers from the user too, thatâ€™s not a big deal. Then we applied a for loop upto any of that numbers and used a condition that if for both the numbers the modulus with loop increment is same, then that is our greatest common divisor of numbers.
