See a solution process below:

Explanation:

Find the prime factors for each number as:

5ab = 5 xx a xx b5ab=5×a×b

6b^2 = 2 xx 3 xx b xx b6b2=2×3×b×b

Now identify the common factors and determine the GCF:

5ab = 5 xx a xx color(red)(b)5ab=5×a×b

6b^2 = 2 xx 3 xx color(red)(b) xx b6b2=2×3×b×b

Therefore:

"GCF" = color(red)(b)GCF=b
