spoj#FACTMULN. Product of factorials (easy)
Product of factorials (easy)
For n positive integer, let F(n) = 1! × 2! × 3! × 4! × ... × n!, product of factorial(i) for i in [1..n].
Let G(n) = {i in [1..n], such that n divides F(i)}.
It is obvious that n belongs to G(n) that makes it a non empty set.
Input
The first line of input contains an integer
T, the number of test cases.
On each of the next T lines, your are given
an integer n.
Output
For each test case, you have to print min(G(n)).
Example
Input: 3 4 5 6
Output: 3 5 3
Explanation
For test case #1:
F(1) = 1! = 1 , not divisible by 4
F(2) = 1! × 2! = 2 , not divisible by 4
F(3) = 1! × 2! × 3! = 12 , divisible by 4
F(4) = 1! × 2! × 3! × 4! = 288 , divisible by 4
So G(4) = {3, 4}.
Constraints
0 < T < 10^4 0 < n < 10^9
A little kB of Python code can get AC in half the time limit. (Edit 2017-02-11, after the compiler changes.)
Input is not randomly chosen ;-) Have fun.
