# GCD and LCM

Time Limit: 2000/1000 MS (Java/Others)

Memory Limit: 65535/65535 K (Java/Others)

## Description

Given two positive integers G and L, could you tell me how many solutions of (x, y, z) there are, satisfying that gcd(x, y, z) = G and lcm(x, y, z) = L?
Note, gcd(x, y, z) means the greatest common divisor of x, y and z, while lcm(x, y, z) means the least common multiple of x, y and z.
Note 2, (1, 2, 3) and (1, 3, 2) are two different solutions.

## Input

First line comes an integer T (T <= 12), telling the number of test cases.
The next T lines, each contains two positive 32-bit signed integers, G and L.
It’s guaranteed that each answer will fit in a 32-bit signed integer.

## Output

For each test case, print one line with the number of solutions satisfying the conditions above.

## Sample Input

2
6 72
7 33 

## Sample Output
