Solve the programming task below in a Python markdown code block.
Alice likes all the numbers which are divisible by A. Bob does not like the numbers which are divisible by B and likes all the remaining numbers. Determine the smallest number greater than or equal to N which is liked by both Alice and Bob. Output -1 if no such number exists.

------ Input Format ------ 

- The first line contains a single integer T — the number of test cases. Then the test cases follow.
- The first and only line of each test case contains three space-separated integers A, B and N — the parameters mentioned in the problem statment.

------ Output Format ------ 

For each test case, output the smallest number ≥ N which is divisible by A and is not divisible by B. Output -1 if no such number exists.

------ Constraints ------ 

$1 ≤ T ≤ 1000$
$1 ≤ A, B, N ≤ 10^{9}$

----- Sample Input 1 ------ 
3
5 2 11
4 3 24
7 7 100

----- Sample Output 1 ------ 
15
28
-1

----- explanation 1 ------ 
Test case $1$: $15$ is the smallest number $≥$ $11$ which is divisible by $5$ and is not divisible by $2$.

Test case $2$: $28$ is the smallest number $≥$ $24$ which is divisible by $4$ and is not divisible by $3$.

Test case $3$: There does not exist any number which is divisible by $A = 7$ and is not divisible by $B = 7$.
