3 is the largest common factor. Therefore, there will be 3 groups with 4 coaches and 14 players. You have to read the question carefully. When I first read the question, I thought I needed to have equal player to coach ratio in each group. I went crazy b/c I have player left over. When I read it several times, I realized I needed to have the same number of coaches per group and the same number of player per group. So the answer to the second part of the questions is 4 coaches and 14 players in each of the 3 groups.
