 Q.no program to calculate the lcm of two number in c-programming.

In this program, we will calculate the lcm (least common multiple ) of two numbers by taking input form the user  in c -programming.

The lcm of two integer a and b is the smallest positive integer that exactly divisible by both the number
(without any remainder), 

#include<stdio.h>
#include<conio.h>
 main()
 {
     int a,b,l;
     printf("enter the two  numbers\n ");
     scanf("%d %d",&a,&b);
     for(l=a>b?a:b;l<=a*b;l++)
     {
         if(l%a==0&&l%b==0)
         {
             printf("the lcm of the two number is %d",l);
             break;
         }
     }
     getch();
 }

 output:      enter the two numbers a=12  and b=16

     

                  the lcm of the two numbers is 48.
