Can someone please explain why? I’m unsure how to fix this - I tried even hard-coding the maximum value for x to be the final answer and it’s not working.

Your code

function smallestCommons(arr) {
// Sort from lowest to highest
arr.sort(function(a, b) {
return a - b;
});
// Function to create the reverse ordered arra
function createArray(array) {
let range = (array[1] - array[0]);
for (let i = 1; i < range; i++) {
array.splice(i,0,array[0]+i);
}
return arr.reverse();
}
// Calling function
createArray(arr);
// Startup values for while loop
let x = 1;
let count = 0
// Loop through 'x' until count reaches the length of the array
while(x) {
x++
for (let i = 0; i <= arr.length; i++) {
if (x % arr[i] == 0) {
count++
} else {
count = 0
}
if (count === arr.length) {
console.log(x)
return x
}
}
}
}
smallestCommons([2,10]);

It’s possible the function is timing out because you’re only incrementing x by 1 on each iteration of the loop. I changed your code so that x is incremented by arr[0] (which is the smallest number in the array) on each iteration because it’s a much more efficient way to do this than incrementing by only 1. Here’s the modified code that passes the test for me:

function smallestCommons(arr) {
// Sort from lowest to highest
arr.sort(function(a, b) {
return a - b;
});
// Function to create the reverse ordered arra
function createArray(array) {
let range = (array[1] - array[0]);
for (let i = 1; i < range; i++) {
array.splice(i,0,array[0]+i);
}
return arr.reverse();
}
// Calling function
createArray(arr);
// Startup values for while loop
let x = 0;
let count = 0
// Loop through 'x' until count reaches the length of the array
while(true) {
x+=arr[0];
for (let i = 0; i <= arr.length; i++) {
if (x % arr[i] == 0) {
count++
} else {
count = 0
}
if (count === arr.length) {
console.log(x)
return x
}
}
}
}
smallestCommons([2,10]);
