The latter depends on whether you are a primary school student or a middle school student.

If middle school students: A 1+A2+A3+A4 = 3 14, A 1

Because A 1, A2, A3, A4 and A5 are all integers, 314 = a1+A2+A3+A4 > = a 1+(a 1+ 1)+(a 1+2)+(a 1+3)= 4a 1+6

a 1 & lt； =77, so the person with the least score will get 77 points at most.

If you are a pupil, please do this:

If you want the person who scores the least to score the most, then the other three people should score as few as possible.

In extreme cases, if the other three people score one point more than the last one, then the total score of these four people is at least 4 times +6 of the one who scored the least.

(404-90-6)/4=77, an integer, is the answer.
