Thank you

#include <iostream>
using namespace std;
int factor(int a, int b);
int main()
{
int x, y;
cout << "This program allows calculating the factor\n";
cout << "Value 1: ";
cin >> x;
cout << "Value 2: ";
cin >> y;
cout << "\nThe Greatest Common factor of "
<< x << " and " << y << " is " << factor(x, y) << endl;
return 0;
}
int factor(int a, int b)
{
while( 1 )
{
a = a / b;
if( a == 0 )
return b;
b = b / a;
if( b == 0 )
return a;
}
}

Hi your main() functions good and the idea behind how you work out the greatest common factor is also fine but you need to make sure when you do the division that the larger of the 2 numbers is divded by the other.
A simple check if a is greater than b allows you to know when to to divide a/b or b/a. The case where they are both equal to each other can be handled by either.
