Hi.
I'm making a C++ program that factors trinomials and I need to find the GCD of 3 numbers. I have a function for finding GCD with 2 numbers.

That function is:
1
2
3
4
5
6
7
8
9
10
11
12
 
int gcd(int number1, int number2)
{
    int c;
    while(1)
    {
  		c = number1 % number2;
  		if (c == 0)
  	  		return b;
  		number1 = number2;
  		number2 = c;
    }
}


Any idea how I could make a formula to find GCD of 3 numbers?
Thanks.

couldn't you just do gcd(gcd(a,b),c)?

and what is the value of "b" in your code there? It only seems to show up on that one line.

Never mind I don't need this.
