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
The number of different groups of students that can be formed from 16 students depends on the size of the groups being formed. If you are looking for all possible combinations of groups of any size (from 1 to 16), you can use the formula for combinations. The total number of combinations would be (2^{16} - 1) (subtracting 1 to exclude the empty group), which equals 65,535 different groups. If you specify a particular group size, the calculation would be different.
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.
they can be 2 groups of 16, 4 groups of 8, 8 groups of 4, or 16 groups of 2
if order does not matter then, (23x22x21x20x19)/(5x4x3x2x1) = 33,649
