Answer: 8
=================================================
Step-by-step explanation:
Add up the three given numbers to get 184+232+272 = 688 people total.
Let's see if 9 is a factor of 688
688/9 = 76.44 approximately which shows 9 is not a factor of 688, and we cannot have teams of 9.
Now let's see if 8 is a factor of 688
688/8 = 86
Therefore, the largest team size is 8 and there would be 86 teams.
