Whats missing from my code here

Tell us what’s happening:

Your code so far


function smallestCommons(arr) {
if(iterate === 0) {
iterate = 1;
} else {
  iterate = (iterate / a) + 1;
}
while( a * iterate % b !== 0) {
  console.log(iterate);
  iterate++;
}
return a * iterate;
}


smallestCommons([1,5]);
