2 * [2344] Minimum Deletions to Make Array Divisible
3 *
4 * You are given two positive integer arrays nums and numsDivide. You can delete any number of elements from nums.
5 * 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.
6 * Note that an integer x divides y if y % x == 0.
7 *  
8 * Example 1:
9 * 
10 * Input: nums = [2,3,2,4,3], numsDivide = [9,6,9,3,15]
11 * Output: 2
12 * Explanation: 
13 * The smallest element in [2,3,2,4,3] is 2, which does not divide all the elements of numsDivide.
14 * We use 2 deletions to delete the elements in nums that are equal to 2 which makes nums = [3,4,3].
15 * The smallest element in [3,4,3] is 3, which divides all the elements of numsDivide.
16 * It can be shown that 2 is the minimum number of deletions needed.
17 * 
18 * Example 2:
19 * 
20 * Input: nums = [4,3,6], numsDivide = [8,2,6,10]
21 * Output: -1
22 * Explanation: 
23 * We want the smallest element in nums to divide all the elements of numsDivide.
24 * There is no way to delete elements from nums to allow this.
25 *  
26 * Constraints:
27 * 
28 * 	1 <= nums.length, numsDivide.length <= 10^5
29 * 	1 <= nums[i], numsDivide[i] <= 10^9
30 *
