C programming, Determine the LCM that is shared by two numbers.

#include <stdio.h>

int main() {

    int n1, n2, max, lcm;

    printf("Enter two positive integers: ");

    scanf("%d %d", &n1, &n2);

    max = (n1 > n2) ? n1 : n2;

    lcm = max;

    while ((lcm % n1 != 0) || (lcm % n2 != 0)) {

        lcm += max;

    }

    printf("The LCM of %d and %d is %d.", n1, n2, lcm);

    return 0;

}
