Problem F. Pave the Parallelepiped

时间限制 1 ms   内存限制 256 MB

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 $$$1\times 2\times 3$$$.

输入数据

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.

输出数据

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

样例说明

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 $$$(2, 2, 2)$$$.
