We can find the GCF by listing the factors of each number and finding the largest factor they have in common. 
The factors are:
24 = 1, 2, 3, 4, 6, 8, 12, 24 
27 = 1, 3, 9, 27 
30 = 1, 2, 3, 5, 6, 10, 15, 30 
The largest factor that all three have in common is 3, so the GCF is 3. Thus, choice D is the correct answer.
