2 * [2427] Number of Common Factors
3 *
4 * Given two positive integers a and b, return the number of common factors of a and b.
5 * An integer x is a common factor of a and b if x divides both a and b.
6 *  
7 * Example 1:
8 * 
9 * Input: a = 12, b = 6
10 * Output: 4
11 * Explanation: The common factors of 12 and 6 are 1, 2, 3, 6.
12 * 
13 * Example 2:
14 * 
15 * Input: a = 25, b = 30
16 * Output: 2
17 * Explanation: The common factors of 25 and 30 are 1, 5.
18 * 
19 *  
20 * Constraints:
21 * 
22 * 	1 <= a, b <= 1000
