HP is doing research in mathematics . After doing lots of research, she struck in a problem . She found four numbers n,a, b and c .Now, She wants to know how many number exists which are less than or equal to n and are divisible by a ,b or c .

Input : First line contains 't' denoting numbers of test cases

Next t lines contains 4 integers denoting n,a,b and c separated by space

Output : 't' lines containing the count of the numbers which are divisible a,b,c

Constraints :

\(1 \le t \le 10^5\)

\(1 \le n \le 10^9\)

\(1 \le a,b,c \le 10^5\)
