**Tell us what’s happening:**

while executing the following program it gives correct result for input [23,18] ie.6056820

but upon executing by the commented code beside the original i.e > by executing the loop backwards i get wrong answer = 2018940

can anyone pls explain why ?

**Your code so far**

```
function smallestCommons(arr) {
let max = Math.max(...arr);
console.log(max) ;
let min = Math.min(...arr);
console.log(min) ;
let no = max ;
for(let i = max;i>=min;i--){ //for(let i=min;i<=max;i++)
if(no%i!=0){
no = no + max ;
i=max ; //i=min
}
}
return no ;
}
console.log(smallestCommons([23,18]));
```
