I have problem , this might be a silly problem for some people but plz. tell me how to solve this problem. NOTED:I am not asking anything related to any ongoing contest.

the problem statement is: Given all the proper (all the divisors except 1 and N) positive divisors of a positive composite integer N, you need to find the value of N. You should assume that the divisors will be given in such a way so that the value of N will always be greater than 1 and less than or equal to 10^12.
