Script Preparation code:

var array = Array.from({ length: 10000 }, () => Math.floor(Math.random() * 10000))

Tests:

sort
array.forEach(n => { const repeat = Math.sqrt(n); const result = [[], []]; for (let i = 1; i <= repeat; i++) { if(n % i === 0) { result.push(i); if (i !== repeat) result.push(n / i); } } result.sort((a, b) => a - b) } )
reverse
array.forEach(n => { const repeat = Math.sqrt(n); const result = [[], []]; for (let i = 1; i < repeat; i++) { if(n % i === 0) { result[0].push(i); result[1].push(n / i); } } if (Number.isInteger(repeat)) result[0].push(repeat) result[1].reverse(); result.flat() } )
