### Re: number of common divisors

For posts of such kind, please provide a brief description of the main idea of your algorithm and don't post your code unless absolutely necessary (e.g getting wrong answer, well even in that case people usually post ideas because most of the time wrong ideas are the reason for wrong answer).
