Solve the programming task below in a Python markdown code block.
The MarkiT online virtual market startup wants to organize its grand opening in NIT Patna.
but they want maximum crowd for their inauguration. So the manager told  this  to Praveen a student in NITP who suggested them:
The first-year students come to campus  every x hour,
Second-year students come to campus every y hour,
Third-year students come to campus every z hour and 
Fourth-year is very busy so they don't come regularly.
So Praveen being very clever told him the no of times in n days he can have an audience of all year student (1st,2nd & 3rd) at max. So can you code what Praveen has done?

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a 2 line of input, first line contain one  integers $N$ (No of Days). 
-Next line contain 3 space separated integer the  value of x y z

-----Output:-----
For each testcase, output in a single line answer the no of times audience consists of all year.

-----Constraints-----
- $1 \leq T \leq 1000$
- $1 \leq N \leq 10^8$
- $1 \leq x,y,z \leq 10^5$

-----Sample Input:-----
1
10
8 10 6

-----Sample Output:-----
2

-----EXPLANATION:-----
First favourable condition will come on 5th day and Second on 10th day.
