Pave the Parallelepiped
Description
You are given a rectangular parallelepiped with sides of positive integer lengths $A$, $B$ and $C$.
Find the number of different groups of three integers ($a$, $b$, $c$) such that $1\leq a\leq b\leq c$ and parallelepiped $A\times B\times C$ can be paved with parallelepipeds $a\times b\times c$. Note, that all small parallelepipeds have to be rotated in the same direction.
For example, parallelepiped $1\times 5\times 6$ can be divided into parallelepipeds $1\times 3\times 5$, but can not be divided into parallelepipeds $1\times 2\times 3$.
The first line contains a single integer $t$ ($1 \leq t \leq 10^5$) — the number of test cases.
Each of the next $t$ lines contains three integers $A$, $B$ and $C$ ($1 \leq A, B, C \leq 10^5$) — the sizes of the parallelepiped.
For each test case, print the number of different groups of three points that satisfy all given conditions.
Input
The first line contains a single integer $t$ ($1 \leq t \leq 10^5$) — the number of test cases.
Each of the next $t$ lines contains three integers $A$, $B$ and $C$ ($1 \leq A, B, C \leq 10^5$) — the sizes of the parallelepiped.
Output
For each test case, print the number of different groups of three points that satisfy all given conditions.

Note
In the first test case, rectangular parallelepiped $(1, 1, 1)$ can be only divided into rectangular parallelepiped with sizes $(1, 1, 1)$.
In the second test case, rectangular parallelepiped $(1, 6, 1)$ can be divided into rectangular parallelepipeds with sizes $(1, 1, 1)$, $(1, 1, 2)$, $(1, 1, 3)$ and $(1, 1, 6)$.
In the third test case, rectangular parallelepiped $(2, 2, 2)$ can be divided into rectangular parallelepipeds with sizes $(1, 1, 1)$, $(1, 1, 2)$, $(1, 2, 2)$ and $(2, 2, 2)$.
