Course Introduction
Programs for practice
Following C++ program ask to the user to enter any two number to find HCF & LCM, then display the result on the screen :
Source Code: Print HCF and LCM of Two Numbers
/* C++ Program - Find HCF and LCM of Two Numbers */
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int a, b, x, y, t, hcf, lcm;
cout<<"Enter two number : ";
cin>>x>>y;
a=x;
b=y;
while(b!=0)
{
t=b;
b=a%b;
a=t;
}
hcf=a;
lcm=(x*y)/hcf;
cout<<"HCF = "<<hcf<<"\n"
cout<<"LCM = "<<lcm<<"\n";
getch();
}
Output
Enter two number:20
8
HCF=4
LCM=40
