WAP to calculate the H.C.F and L.C.M of three numbers.

eg.  H.C.F of 11,22,33 is 11
      L.C.M of 11,22,33 is 66

-------------------------------------

     H.C.F of 2,3,4 is 1
     L.C.M of 2,3,4 is 24

#include<iostream.h>
#include<conio.h>
void main()
{
int a, b, c; // three numbers
int hcf,lcm;

//calculate the minimum of three numbers
int min = (a < b ? a : b);
min = (min < c ? min : c);

for( int i = min; i>0; i--)
{
if(a%i == 0 && b%i == 0 && c%i == 0)
{
  hcf = i;
  break;
  }
}

lcm = (a*b*c)/hcf;

cout<<" \n The H.C.F of " << a <<" , " << b << " , " << c << "is " << hcf;

cout<<" \n The L.C.M of " << a <<" , " << b << " , " << c << "is " << lcm;

getch();

}  

/*  Similarly you can calculate HCF of 2 numbers or 4 numbers and so on. */

C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do it blows your whole leg off.
