Please explain what is happening in this code

JavaScript

I took this from the hints, and not following the logic and code blocks and statements. can someone break this down for me please?

  **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;
  }
}
}
