SMALL - Smallest Number

Your Task is extremely simple, for a given number N you have to find the smallest number which is divisible by all numbers from 1 to N without leaving any remainder, As number can be very large print the answer modulo 1000000007.


Input starts with a positive integer T < 501 in a single line, then T lines follow. Each of the T lines contains one positive integer N < 10001.


For every N print the desired number.

No precomputation needed
AC @0.00s :)

@Lakshman would you check whats wrong with my code..its giving correct answers for every test cases I borrowed from spoj toolkit.But still showing wrong answer.Please reply soon.18238934 is the id
Somebody please help!! I think it has something yo do with the input/output thing.Btw I am new to spoj

Read 1000000007 as 10**8 + 7. Got 1 WA :( then got AC.

Superb question.
Keep in mind: LCM(a,b,c) = LCM(a,LCM(b,c))
BUT, LCM(a,b,c)%mod != LCM(a,LCM(b,c)%mod) %mod
With C/C++ it might end up in overflows. Try a different approach!

Python like languages are unfair to this question :( . Beautiful question with a peasant solution in Python.

==(Lakshman)=> Here is the medium version

Re: Thanks :) ! You can also add it to the problem description! :)

Same Logic In Python Gives AC
And C++ WA.

==(Lakshman)=>why don't you check your both answers of Python and c++?. Wrong answer in c++ is because of overflow.
