C program to find Greatest Common Divisor (GCD ) of two given integers

#include <stdio.h>
int main()
{
    int n1, n2, i, gcd;

    printf("Enter two integers: ");
    scanf("%d %d", &n1, &n2);

    for(i=1;i <= n1 && i <= n2; i++)
    {
        if(n1%i==0 && n2%i==0)
        gcd = i;
    }
    printf("%d", gcd);
}
