The GCF of 16, 18, and 30 is 2. The GCF of the set can't be any greater than the smallest difference between two numbers in the set. The difference between 16 and 18 is 2, and so that's the highest possible GCF. Noting that each number in the set is even, we then know that the GCF is, in fact, 2.
The GCF is 2.
