Optimization (CodeWars Integers: Recreation One)

I managed to find two algos for this CodeWars challenge (https://www.codewars.com/kata/integers-recreation-one/train/javascript). Unfortunately, they are not fast enough (> 12000ms).

Any suggestions on how to improve my code ?

v1 :

const listSquared = (m, n) => {
const result = ;
for (let i = m; i <= n; i++) {
const divisorsOfi = ;
for (let j = 0; j <= i; j++) {
if (i % j === 0) {
divisorsOfi.push(Math.pow(j, 2))
}
}
let sumOfDivisorsOfi = 1;
if (divisorsOfi.length > 1) {
sumOfDivisorsOfi = divisorsOfi.reduce((a, b) => a + b);
}
if (Number.isInteger(Math.sqrt(sumOfDivisorsOfi))) {
result.push([i, sumOfDivisorsOfi]);
}
}
return result;
}


v2:

const listSquared = (m, n) => {
const result = ;
for (let i = m; i <= n; i++) {
let sumOfSqrtDivisorsOfi = divisors(i);
if (Number.isInteger(Math.sqrt(sumOfSqrtDivisorsOfi))) {
result.push([i, sumOfSqrtDivisorsOfi]);
}
}
return result;
}

const divisors = (n) => [...Array(n + 1).keys()].slice(1)
.reduce((s, a) => s + (!(n % (a)) && Math.pow(a, 2)), 0);


Thanks in advance !
