#include <stdio.h> int main() { int n1, n2, i, gcd, lcm; printf("Enter two positive integers: "); scanf("%d %d", &n1, &n2); for (i = 1; i <= n1 && i <= n2; ++i) { // check if i is a factor of both integers if (n1 % i == 0 && n2 % i == 0) gcd = i; } lcm = (n1 * n2) / gcd; printf("The LCM of two numbers %d and %d is %d.", n1, n2, lcm); return 0; }
Output:
Enter two positive integers: 72 120 The LCM of two numbers 72 and 120 is 360.
