To divide a class of 32 students into groups with equal numbers of students, you would need to find the factors of 32. The factors of 32 are 1, 2, 4, 8, 16, and 32. Therefore, you can divide the class into 1 group of 32 students, 2 groups of 16 students, 4 groups of 8 students, 8 groups of 4 students, 16 groups of 2 students, or 32 groups of 1 student. So, there are 6 ways to divide the class into groups with equal numbers of students.
they can be 2 groups of 16, 4 groups of 8, 8 groups of 4, or 16 groups of 2

You could have 15 groups, with 1 coach and 2 students in each group.Out of the 50 participants, 90% would be active . . . only five studentswould be left out.
20 x 19 x 18/3 x 2 = 1,140 groups
2 groups. 2 x 3= 6
23 x 22 x 21 x 20/4 x 3 x 2 = 8,855 groups

There are only two possibilities... 10 groups of 2 or 5 groups of 4. Unless - you can have varying sized groups - which you didn't specify.

if order does not matter then, (23x22x21x20x19)/(5x4x3x2x1) = 33,649
