LCM program in c with two numbers:

Definition of LCM (Least common multiple):

LCM of two integers is a smallest positive integer which is multiple of both integers that it is divisible by the both of the numbers.

For example: LCM of two integers 2 and 5 is 10 since 10 is the smallest positive numbers which is divisible by both 2 and 5.

#include<stdio.h>

int main(){

  int n1,n2,x,y;

  printf("\nEnter two numbers:");

  scanf("%d %d",&n1,&n2);

  x=n1,y=n2;

  while(n1!=n2)

  {

      if(n1>n2)

           n1=n1-n2;

      else

           n2=n2-n1;

  }

  printf("L.C.M=%d",x*y/n1);

  return 0;
