They are not the least or the smallest common denominators.
Sorry but can you please explain that more.
The least common denominator of 3/4 and 4/8 is 8. It's the smallest number divisible by both 4 and 8.
The least common denominator of 5/9 and 7/12 is 36. It's the smallest number divisible by both 9 and 12.
Ms. Sue i am very sorry but please explain that with more details.
These sites have excellent explanations.

But what do they mean when they say the product of 4 and 8 and of 9 and 12?
Product is the answer to a multiplication problem.
