Calculate sum of all integers strictly less than $N$ that are divisble by both $a$ and $b$. Since this number could be very large, compute it modulo $10^{9}+7$. ###Input: - First line will contain $T$, number of testcases. Then the testcases follow. - Each testcase contains of a single line of input, three integers $N,a,b$. ###Output: For each testcase, output in a single line answ
