题目描述
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 $1\times 2\times 3$ .

输入格式
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.

输出格式
For each test case, print the number of different groups of three points that satisfy all given conditions.
