    "task_description": "You are given two positive integer arrays `nums` and `numsDivide`. You can delete any number of elements from `nums`. Return _the **minimum** number of deletions such that the **smallest** element in _`nums`_ **divides** all the elements of _`numsDivide`. If this is not possible, return `-1`. Note that an integer `x` divides `y` if `y % x == 0`. **Example 1:** ``` **Input:** nums = [2,3,2,4,3], numsDivide = [9,6,9,3,15] **Output:** 2 **Explanation:** The smallest element in [2,3,2,4,3] is 2, which does not divide all the elements of numsDivide. We use 2 deletions to delete the elements in nums that are equal to 2 which makes nums = [3,4,3]. The smallest element in [3,4,3] is 3, which divides all the elements of numsDivide. It can be shown that 2 is the minimum number of deletions needed. ``` **Example 2:** ``` **Input:** nums = [4,3,6], numsDivide = [8,2,6,10] **Output:** -1 **Explanation:** We want the smallest element in nums to divide all the elements of numsDivide. There is no way to delete elements from nums to allow this. ``` **Constraints:** `1 <= nums.length, numsDivide.length <= 105` `1 <= nums[i], numsDivide[i] <= 109`",
