C program to find GCD of given numbers

#include <stdio.h>
int main()
{
	int n1, n2, i, gcd;
	
	printf("Enter two integers: ");
	scanf("%d %d", &n1, &n2);
	
	i=1;
	while(i<=n1 && i<=n2)
	{
		if(n1%i==0 && n2%i==0)
		{
			gcd = i;
		}
		++i;
	}
	printf("G.C.D of %d and %d is %d", n1, n2, gcd);
	return 0;
}
