Hello
This is code from the solution of this challenge. I can’t quite understand the const numberDivisors part on line 4. What’s the purpose of that
**Your code so far**
function smallestCommons(arr) {
// Setup
const [min, max] = arr.sort((a, b) => a - b);
const numberDivisors = max - min + 1;
// Largest possible value for SCM
let upperBound = 1;
for (let i = min; i <= max; i++) {
upperBound *= i;
}
// Test all multiples of 'max'
for (let multiple = max; multiple <= upperBound; multiple += max) {
// Check if every value in range divides 'multiple'
let divisorCount = 0;
for (let i = min; i <= max; i++) {
// Count divisors
if (multiple % i === 0) {
divisorCount += 1;
}
}
if (divisorCount === numberDivisors) {
return multiple;
}
}
}
smallestCommons([1, 5]);
