COMDIV - Number of common divisors
You will be given T (T ≤ 106) pairs of numbers. All you have to tell is the number of common divisors between the 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 ≤ 106)
Output
One integer describing number of common divisors between two numbers.
Example
Input: 3
100000 100000
12 24
747794 238336 Output: 36
6
2

Try to solve in O(T* logT) ,

Weak Test Cases, O(T * Sqrt(gcd(a,b))) shouldn't be passed. |

1. ___gcd(a,b)

find prime divisors of the gcd(a,b) using seive, |

weak test cases i guess! O(T * sqrt(gcd(a, b))) passes the test cases. It should be 10 ^ 6 * 10 ^ 3 in worst case. O(T * log(gcd(a, b))) good approach tho. |

Important - 1 is also considered a factor. It cost me a wrong answer. |

Use "\n" instead of endl to avoid TLE. |

AC in one go. No scanf,printf used. Complexity-->O(logn + sqrt(n)) |

I got an AC without using scanf and printf |
