You are an expert competitive programmer. You will be given a problem statement, test case constraints and example test inputs and outputs. Please reason step by step about the solution (that must respect memory and time limits), then provide a complete implementation in python3.

Your solution must read input from standard input (cin), write output to standard output (cout).
Do not include any debug prints or additional output.

Put your final solution within a single code block:
```python
<your code here>
```

Execution time limit: 1.0 seconds

# Problem
Alexander is a well-known programmer. Today he decided to finally go out and play football, but with the first hit he left a dent on the new Rolls-Royce of the wealthy businessman Big Vova. Vladimir has recently opened a store on the popular online marketplace "Zmey-Gorynych", and offers Alex a job: if he shows his programming skills by solving a task, he'll work as a cybersecurity specialist. Otherwise, he'll be delivering some doubtful products for the next two years.

You're given $$$n$$$ positive integers $$$a_1, a_2, \dots, a_n$$$. Using each of them exactly at once, you're to make such sequence $$$b_1, b_2, \dots, b_n$$$ that sequence $$$c_1, c_2, \dots, c_n$$$ is lexicographically maximal, where $$$c_i=GCD(b_1,\dots,b_i)$$$ - the greatest common divisor of the first $$$i$$$ elements of $$$b$$$.

Alexander is really afraid of the conditions of this simple task, so he asks you to solve it.

A sequence $$$a$$$ is lexicographically smaller than a sequence $$$b$$$ if and only if one of the following holds:

- $$$a$$$ is a prefix of $$$b$$$, but $$$a \ne b$$$;
- in the first position where $$$a$$$ and $$$b$$$ differ, the sequence $$$a$$$ has a smaller element than the corresponding element in $$$b$$$.

## Input Format
Each test contains multiple test cases. The first line contains the number of test cases $$$t$$$ ($$$1 \le t \le 10^3$$$). Description of the test cases follows.

The first line of each test case contains a single integer $$$n$$$ ($$$1 \le n \le 10^3$$$)  — the length of the sequence $$$a$$$.

The second line of each test case contains $$$n$$$ integers $$$a_1,\dots,a_n$$$ ($$$1 \le a_i \le 10^3$$$)  — the sequence $$$a$$$.

It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$10^3$$$.

## Output Format
For each test case output the answer in a single line  — the desired sequence $$$b$$$. If there are multiple answers, print any.

## Examples
```input
7
2
2 5
4
1 8 2 3
3
3 8 9
5
64 25 75 100 50
1
42
6
96 128 88 80 52 7
5
2 4 8 16 17
```
```output
5 2 
8 2 1 3 
9 3 8 
100 50 25 75 64 
42 
128 96 80 88 52 7 
17 2 4 8 16
```

## Note
In the first test case of the example, there are only two possible permutations $$$b$$$  — $$$[2, 5]$$$ and $$$[5, 2]$$$: for the first one $$$c=[2, 1]$$$, for the second one $$$c=[5, 1]$$$.

In the third test case of the example, number $$$9$$$ should be the first in $$$b$$$, and $$$GCD(9, 3)=3$$$, $$$GCD(9, 8)=1$$$, so the second number of $$$b$$$ should be $$$3$$$.

In the seventh test case of the example, first four numbers pairwise have a common divisor (a power of two), but none of them can be the first in the optimal permutation $$$b$$$.

Now solve the problem and return the code.
