**Tell us what’s happening:**

Why does my code not pass the last two cases? It worked on my own laptop.

**Your code so far**

```
function smallestCommons(arr) {
let mutl = Math.max(...arr);
let rag = [];
for(let i=Math.min(...arr); i<=Math.max(...arr); i++) {
rag.push(i);
}
while(1) {
if(rag.map((e)=>(mutl%e === 0)).every((a)=>(a === true))) {
break;
}
mutl +=1;
}
return mutl;
}
smallestCommons([1,5]);
```
