## Introduction

Write C program to find LCM of any two numbers.

### What is LCM?

Least Common Multiple (L.C.M.) of two natural numbers is the smallest natural number which is a multiple of both the numbers.

For example, the hcf of 20 and 60 is 60

#include <stdio.h> int main() { int i, num1, num2, max, cm=1; // Reading two numbers from user printf("Enter any two: "); scanf("%d%d", &num1, &num2); // Find max number between num1 and num2 max = (num1 > num2) ? num1 : num2; i = max; //Loop runs forever till lcm is not found while(1) { if(i%num1 == 0 && i%num2 == 0) { //If i divides both num1 and num2 then lcm is found hence exit from loop cm = i; break; } //If lcm is not found then generate next multiple of max between both numbers i += max; } printf("LCM of %d and %d = %d", num1, num2, cm); return 0; }
