COMDIV - Number of common divisors
You will be given T (T<=10^6) pair of numbers. All you have to tell is the number of common divisors between two numbers in each pair.
Input
First line of input: T (Number of test cases)
In next T lines, each have one pair A B (0 < A, B <= 10^6)
Output
One integer describing number of common divisors between two numbers.
Example
Input: 3
100000 100000
12 24
747794 238336
Output: 36
6

The trick here is that, the divisors of the gcd(a, b) is the answer [Let a, b be the given pair].

Only a single cin and cout will cost you TLE don't need to seive just find gcd and then count divisor

Here is a note about comparing the same solution speed across different programming languages:
