Acoach is dividing a soccer team of 28 players into groups. if each group has the same number of players, what is the greatest number of groups there can be if each group has no more than 10 players?

The only possible groups that could be made if each group have the same number of people is 2 groups of 14 or 4 groups of 7. Since each group cannot have more than 10 people, the only group left is 4 groups of 7.
