I am having some trouble with this problem: What characteristics do the numbers 8, 10, 15, 26 and 33 have that the numbers 5, 9, 16, 18, and 24 don't have? ( Hint: List the factors of the numbers.) Give two numbers that have this characteristic. Here is my answer: 8, 10, 15, 26, 33 each have four distinct factions. Another 2 numbers that have this characteristic are: 6 and 27. Did I answer this right? Could you explain it to me if my answer is not right? Thanks.

What do you mean have four distinct "fractions"? Please explain to me how 26 has four distinct "fractions".

This same question has appeared before.
I ignored it at the time since I thought it was a silly question.
Just about as absurd as
"What characteristics do the numbers 2, 3 10 12 12 have that the numbers 1, 4, 5, 6, 7, 8, 9, 11, 14 don't have?"
answer: When sounded out in English the first set starts with the letter "t"

My Lord. And this is in math class? Drop the class, if not drop the school.

Here is my answer: 8, 10, 15, 26, 33 each have four distinct factors. Another 2 numbers that have this characteristic are: 6 and 27. Did I answer this right? Could you explain it to me if my answer is not right? Thanks.
B.B. In my opinion I think your explanation holds water after the minor typo correction. There was a hint about listing the factors. Yes, 6 and 27 both have 4 factors, counting 1 and the number itself.
I was thinking along the same lines in the previous posted question, but since I did not list the factors explicitly, and in my mind, I only counted prime factors, so I missed.
