**Tell us what’s happening:**

Hi guys. I wrote the first block of this code, but the rest comes from the solution, which I shamefully had to look at. It works, and I understand what is going on for the most part, except for one thing:

In line 14, where I wrote console.log(GCD), I get this list of numbers: 1, 2, 1, 6, 5, 4, 3, 2. The 1, 2, 1 is what I would expect from the formula in findGCD, but can someone explain where the 6, 5, 4, 3, 2 come from? Numbers I cannot wrap my head around appear on the console, no matter which parameter I use from the problem. I’m just not following the logic. Thanks.

**Your code so far**

```
function smallestCommons(arr) {
arr.sort(function(a, b ) {
return b-a;
});
var sorted = [];
for (var i = arr[0]; i >= arr[1]; i--) {
sorted.push(i);
}
var lcm = sorted[0];
for (var i = 1; i < sorted.length; i++) {
var GCD = findGCD(lcm, sorted[i]);
console.log(GCD);
var lcm = (lcm * sorted[i]) / GCD;
}
return lcm;
function findGCD(x, y) {
if (y === 0) {
return x;
}
else {
return findGCD(y, x % y);
}
}
}
smallestCommons([2, 10]);
```
