Well you could divide:
24 groups of 1 egg each
12 groups of 2 eggs each
8 groups of 3 eggs each
6 groups of 4 eggs each
4 groups of 6 eggs each
3 groups of 8 eggs each
2 groups of 12 eggs each
1 group of 24 eggs
Note how if you multiply the number of groups times the number of eggs it contains, gives you 24
