CF1933C.Turtle Fingers: Count the Values of k
Turtle Fingers: Count the Values of k
You are given three positive integers , and ().
It can be shown that there always exists a way to choose non-negative (i.e. ) integers , , and such that .
Your task is to find the number of distinct possible values of across all such ways.
Input
The first line contains the integer () — the number of test cases.
The following lines contain three integers, , and (, ) — description of a test case.
Output
Output lines, with the -th () line containing an integer, the answer to the -th test case.
Note
In the first test case, . The possible values of (and corresponding ) are as follows:
- Choose . Then $k \cdot a^x \cdot b^y = 1 \cdot 2^2 \cdot 5^1 = 20 = l$.
- Choose . Then $k \cdot a^x \cdot b^y = 2 \cdot 2^1 \cdot 5^1 = 20 = l$.
- Choose . Then $k \cdot a^x \cdot b^y = 4 \cdot 2^0 \cdot 5^1 = 20 = l$.
- Choose . Then $k \cdot a^x \cdot b^y = 5 \cdot 2^2 \cdot 5^0 = 20 = l$.
- Choose . Then $k \cdot a^x \cdot b^y = 10 \cdot 2^1 \cdot 5^0 = 20 = l$.
- Choose . Then $k \cdot a^x \cdot b^y = 20 \cdot 2^0 \cdot 5^0 = 20 = l$.
In the second test case, . Note that is not divisible by either or . Therefore, we can only set , which corresponds to .
In the third test case, . The possible values of (and corresponding ) are as follows:
- Choose . Then $k \cdot a^x \cdot b^y = 2 \cdot 4^1 \cdot 6^1 = 48 = l$.
- Choose . Then $k \cdot a^x \cdot b^y = 3 \cdot 4^2 \cdot 6^0 = 48 = l$.
- Choose . Then $k \cdot a^x \cdot b^y = 8 \cdot 4^0 \cdot 6^1 = 48 = l$.
- Choose . Then $k \cdot a^x \cdot b^y = 12 \cdot 4^1 \cdot 6^0 = 48 = l$.
- Choose . Then $k \cdot a^x \cdot b^y = 48 \cdot 4^0 \cdot 6^0 = 48 = l$.
