Leetcode 2470. Number of Subarrays With LCM Equal to K

Count the number of contiguous subarrays whose least common multiple equals k, using the key observation that any subarray LCM must divide k so you can accumulate LCMs and stop when it no longer divides k. With nums.length and values ≤1000, an O(n^2) scan is feasible.
