题目描述
You are given three positive integers $a$ , $b$ and $l$ ( $a,b,l>0$ ).
It can be shown that there always exists a way to choose non-negative (i.e. $\ge 0$ ) integers $k$ , $x$ , and $y$ such that $l = k \cdot a^x \cdot b^y$ .
Your task is to find the number of distinct possible values of $k$ across all such ways.

输入格式
The first line contains the integer $t$ ( $1 \le t \le 10^4$ ) — the number of test cases.
The following $t$ lines contain three integers, $a$ , $b$ and $l$ ( $2 \le a, b \le 100$ , $1 \le l \le 10^6$ ) — description of a test case.

说明/提示
In the first test case, $a=2, b=5, l=20$ . The possible values of $k$ (and corresponding $x,y$ ) are as follows:
- Choose $k = 1, x = 2, y = 1$ . Then $k \cdot a^x \cdot b^y = 1 \cdot 2^2 \cdot 5^1 = 20 = l$ .
- Choose $k = 2, x = 1, y = 1$ . Then $k \cdot a^x \cdot b^y = 2 \cdot 2^1 \cdot 5^1 = 20 = l$ .
- Choose $k = 4, x = 0, y = 1$ . Then $k \cdot a^x \cdot b^y = 4 \cdot 2^0 \cdot 5^1 = 20 = l$ .
- Choose $k = 5, x = 2, y = 0$ . Then $k \cdot a^x \cdot b^y = 5 \cdot 2^2 \cdot 5^0 = 20 = l$ .
- Choose $k = 10, x = 1, y = 0$ . Then $k \cdot a^x \cdot b^y = 10 \cdot 2^1 \cdot 5^0 = 20 = l$ .
- Choose $k = 20, x = 0, y = 0$ . Then $k \cdot a^x \cdot b^y = 20 \cdot 2^0 \cdot 5^0 = 20 = l$ .
In the second test case, $a=2, b=5, l=21$ . Note that $l = 21$ is not divisible by either $a = 2$ or $b = 5$ . Therefore, we can only set $x = 0, y = 0$ , which corresponds to $k = 21$ .
In the third test case, $a=4, b=6, l=48$ . The possible values of $k$ (and corresponding $x,y$ ) are as follows:
- Choose $k = 2, x = 1, y = 1$ . Then $k \cdot a^x \cdot b^y = 2 \cdot 4^1 \cdot 6^1 = 48 = l$ .
- Choose $k = 3, x = 2, y = 0$ . Then $k \cdot a^x \cdot b^y = 3 \cdot 4^2 \cdot 6^0 = 48 = l$ .
- Choose $k = 8, x = 0, y = 1$ . Then $k \cdot a^x \cdot b^y = 8 \cdot 4^0 \cdot 6^1 = 48 = l$ .
- Choose $k = 12, x = 1, y = 0$ . Then $k \cdot a^x \cdot b^y = 12 \cdot 4^1 \cdot 6^0 = 48 = l$ .
- Choose $k = 48, x = 0, y = 0$ . Then $k \cdot a^x \cdot b^y = 48 \cdot 4^0 \cdot 6^0 = 48 = l$ .
- Choose $k = 1, x = 2, y = 1$ . Then $k \cdot a^x \cdot b^y = 1 \cdot 2^2 \cdot 5^1 = 20 = l$ .
- Choose $k = 2, x = 1, y = 1$ . Then $k \cdot a^x \cdot b^y = 2 \cdot 2^1 \cdot 5^1 = 20 = l$ .
- Choose $k = 4, x = 0, y = 1$ . Then $k \cdot a^x \cdot b^y = 4 \cdot 2^0 \cdot 5^1 = 20 = l$ .
- Choose $k = 5, x = 2, y = 0$ . Then $k \cdot a^x \cdot b^y = 5 \cdot 2^2 \cdot 5^0 = 20 = l$ .
- Choose $k = 10, x = 1, y = 0$ . Then $k \cdot a^x \cdot b^y = 10 \cdot 2^1 \cdot 5^0 = 20 = l$ .
- Choose $k = 20, x = 0, y = 0$ . Then $k \cdot a^x \cdot b^y = 20 \cdot 2^0 \cdot 5^0 = 20 = l$ .
In the second test case, $a=2, b=5, l=21$ . Note that $l = 21$ is not divisible by either $a = 2$ or $b = 5$ . Therefore, we can only set $x = 0, y = 0$ , which corresponds to $k = 21$ .
In the third test case, $a=4, b=6, l=48$ . The possible values of $k$ (and corresponding $x,y$ ) are as follows:
- Choose $k = 2, x = 1, y = 1$ . Then $k \cdot a^x \cdot b^y = 2 \cdot 4^1 \cdot 6^1 = 48 = l$ .
- Choose $k = 3, x = 2, y = 0$ . Then $k \cdot a^x \cdot b^y = 3 \cdot 4^2 \cdot 6^0 = 48 = l$ .
- Choose $k = 8, x = 0, y = 1$ . Then $k \cdot a^x \cdot b^y = 8 \cdot 4^0 \cdot 6^1 = 48 = l$ .
- Choose $k = 12, x = 1, y = 0$ . Then $k \cdot a^x \cdot b^y = 12 \cdot 4^1 \cdot 6^0 = 48 = l$ .
- Choose $k = 48, x = 0, y = 0$ . Then $k \cdot a^x \cdot b^y = 48 \cdot 4^0 \cdot 6^0 = 48 = l$ .
