All submissions for this problem are available.### Read problems statements in [Mandarin Chinese](http://www.codechef.com/download/translated/MARCH14/mandarin/ANUGCD.pdf) and [Russian](http://www.codechef.com/download/translated/MARCH14/russian/ANUGCD.pdf).
### Statement
You will be given an array **A** of **N** integers. You need to answer **M** queries.
Each query is of the form **G x y**.
For each query, construct the set **S** from **A**. **A\[i\]** is included in **S** if **x** <= **i** <= **y** and **GCD(G,A\[i\])** > 1.
Let **MAX** be the maximum number present in **S**. Output **MAX** and number of occurances of **MAX** in **S**.
If no such number exists, output "**-1 -1**" (without quotes).
### Input
The first line of the input contains 2 integers **N** and **M**.
Next line has **N** integers representing the elements of array **A**.
**M** lines follow, one per query. Each line has 3 integers **G**, **x** and **y**
### Output
For each query output the required Answer.
### Constraints
- **1** ≤ **N,M,G,A\[i\]** ≤ **100000** (**1** ≤ **i** ≤ **N**)
- **1** ≤ **x** ≤ **y** ≤ **N**
### Example
<pre><b>Input</b>
6 5
1 2 3 4 5 4
2 1 5
121 1 6
3 2 6
5 5 5
24 4 6
<b>Output</b>
4 1
-1 -1
3 1
5 1
4 2
</pre>### Explanation
**Query #1**
GCD(2,1)=1, GCD(2,2)=2, GCD(2,3)=1, GCD(2,4)=2, GCD(2,5)=1
S = {2,4}
MAX = 4
**Query #2**
S = {}
There is no element in **A** such that GCD(121, A\[i\])>1
**Query #5**
GCD(24,4)=4, GCD(24,5)=1, GCD(24,4)=4
S = {4,4}
MAX = 4
Answer is "4 2" as there are 2 occurances of 4 in **S**
