Given an integer array nums and an integer k, return the number of subarrays of nums where the least common multiple of the subarray's elements is k.

\n\n

A subarray is a contiguous non-empty sequence of elements within an array.

\n\n

The least common multiple of an array is the smallest positive integer that is divisible by all the array elements.

\n\n

Example 1:

\n\n
\nInput: nums = [3,6,2,7,1], k = 6\nOutput: 4\nExplanation: The subarrays of nums where 6 is the least common multiple of all the subarray's elements are:\n- [3,6,2,7,1]\n- [3,6,2,7,1]\n- [3,6,2,7,1]\n- [3,6,2,7,1]\n
\n\n

Example 2:

\n\n
\nInput: nums = [3], k = 2\nOutput: 0\nExplanation: There are no subarrays of nums where 2 is the least common multiple of all the subarray's elements.\n
