title: lcm of zero and other interger
body: <p>As I know, LCM(Least Common Multiple) of 3 and 5 is 15. That means we can divide 15 with both 3 and 5 without any remainder.</p>
  <p>Similarly LCM of 0 and 5 is 0. So We also can divide 0 with both 5 and 0.</p>
  <p>But we all know that we cannot divide 0 with 0. So LCM of 0 and other integer is not 0.</p>
  <p>Please explain me .</p>
