Given X and Y as the GCD and LCM of two numbers A and B. Find all possible pairs of (A,B).
Note: (a, b) and (b, a) are considered as two different pairs.

Example 1:

Input: x = 2, y = 12
Output: 4
Explaination: The pairs are (2, 12), 
(4, 6), (6, 4) and (12, 2).


Example 2:

Input: x = 3, y = 6
Output: 2
Explaination: The pairs are (3, 6) and 
(6, 3).


Example 3:

Input: x = 6, y = 4
Output: 0
Explaination: There is no such pair such 
that gcd is 6 and lcm is 4.


Your Task:
You do not need to read input or print anything. Your task is to complete the function pairCount() which takes x and y as input parameters and returns the number of possibe pairs.


Expected Time Complexity: O(sqrt(N)*LogN)    [N is maximum of x and y]
Expected Auxiliary Space: O(1)


Constraints:
1 ≤ x, y ≤ 104
