  int a,b,hcf,lcm,max,min,r;
 
  cout<<"Enter Two Numbers: \n";
  cin>>a>>b;

if(a>b)
{
  max=a;
  min=b;
}
else if(b>a)
{
  max=b;
  min=a;
}
if(a==b)
  hcf=a;
else
{
  do
  {
  r=max%min;
  max=min;
  min=r;
  }while(r!=0);
  hcf=max;
}
  lcm=(a*b)/hcf;
  cout<<"\nLCM = "<<lcm<<"\nHCF = "<<hcf;
  return 0;
}

Output:-
