Smallest Common Multiple Issue

Tell us what’s happening:

Hi all, I can’t understand something about this Challenge. Does he acquire the smallest common multiple number so according to my knowledge for 1 5 as example = 5 because 1+1+1+1+1 = 5 and 5 , so it’s the smallest common multiple number, so why he gives 60 ?!

Your code so far

function smallestCommons(arr) {
  var multi0 = [];
  var multi1 = [];
  var sum0 = 0;
  for (var i = 0 ; i < 300 ; i ++){
    sum0 = arr[0] + sum0;  
    multi0.push(sum0);
  }
  var sum1 = 0;
  for (var j = 0 ; j < 300 ; j ++){
    sum1 = arr[1] + sum1;  
    multi1.push(sum1);
  }
  var common = [];
  for (var k =0 ; k <300 ; k++){
 if(multi1.indexOf(multi0[k]) !== -1){
   common.push(multi0[k]);
 }
  }
  return common;
}


smallestCommons([23,18]);
