You are given an array nums that consists of positive integers.

\n\n

The GCD of a sequence of numbers is defined as the greatest integer that divides all the numbers in the sequence evenly.

\n\n\n\n

A subsequence of an array is a sequence that can be formed by removing some elements (possibly none) of the array.

\n\n\n\n

Return the number of different GCDs among all non-empty subsequences of nums.

Example 1:

\n\"\"\n
\nInput: nums = [6,10,3]\nOutput: 5\nExplanation: The figure shows all the non-empty subsequences and their GCDs.\nThe different GCDs are 6, 10, 3, 2, and 1.\n
