Jenny places a total of 18 red Easter eggs in several green baskets and a total of 24 orange Easter eggs in some blue baskets. Each basket contains the same number of eggs and there are at least 4 eggs in each basket. How many eggs did Jenny put in each basket?

The number of eggs in each basket is a common divisor of 18 and 24 that is at least 4. The common divisors of 18 and 24 are 1, 2, 3, and 6, so there are 6 eggs in each basket.
