**Tell us what’s happening:**

Can anyone please help me out where is the bug and why this doesn’t work?

**Your code so far**

```
function smallestCommons(arr) {
/* let output=[]; */
function arr1(numOne){
let increment=numOne;
let newOne=[];//should be console
for(let i=1;i<10;i++){
newOne.push(numOne+increment);
numOne+=increment;
}
return newOne;
}
/* function arr2(numTwo){
let newIncrement=numTwo;
let newArr=[numTwo];
for(let j=1;j<10;j++){
newArr.push(numTwo+newIncrement);
numTwo+=newIncrement;
}
return newArr;
} */
let array1=arr1(arr[0]);
let array2=arr1(arr[1]);
function common(one, two) {
let result=one.filter(value => -1 !== two.indexOf(value));
return result
}
let newArray=common(array1,array2);
let finalResult=Math.min.apply(null,newArray);
return finalResult;
}
smallestCommons([1, 5]);
```
