codeforces#P1855B. Longest Divisors Interval
Longest Divisors Interval
Description
Given a positive integer $n$, find the maximum size of an interval $[l, r]$ of positive integers such that, for every $i$ in the interval (i.e., $l \leq i \leq r$), $n$ is a multiple of $i$.
Given two integers $l\le r$, the size of the interval $[l, r]$ is $r-l+1$ (i.e., it coincides with the number of integers belonging to the interval).
The first line contains a single integer $t$ ($1 \le t \le 10^4$) — the number of test cases.
The only line of the description of each test case contains one integer $n$ ($1 \leq n \leq 10^{18}$).
For each test case, print a single integer: the maximum size of a valid interval.
Input
The first line contains a single integer $t$ ($1 \le t \le 10^4$) — the number of test cases.
The only line of the description of each test case contains one integer $n$ ($1 \leq n \leq 10^{18}$).
Output
For each test case, print a single integer: the maximum size of a valid interval.

Note
In the first test case, a valid interval with maximum size is $[1, 1]$ (it's valid because $n = 1$ is a multiple of $1$) and its size is $1$.
In the second test case, a valid interval with maximum size is $[4, 5]$ (it's valid because $n = 40$ is a multiple of $4$ and $5$) and its size is $2$.
In the third test case, a valid interval with maximum size is $[9, 11]$.
In the fourth test case, a valid interval with maximum size is $[8, 13]$.
In the seventh test case, a valid interval with maximum size is $[327869, 327871]$.
