Each group will have students. The factors of 8 are 1, 2, 4, 8. The factors of 28 are 1, 2, 4, 7, 14, 28. The of 8 and 28 is 4.

If each group has the greatest possible number of club members, how many groups of sixth graders and how many groups of seventh graders will there be? Complete the statements.


There will be groups of sixth graders and groups of seventh graders. This is because 8 = 4 × and 28 = 4 × .
