A composite number is a positive integer which has a positive divisor other than one or itself. By definition, every integer greater than one is either a prime number or a composite number. The numbers zero and one are considered to be neither prime nor composite.
23 and 47 are both prime numbers
28 and 33 are both composite numbers
28 has 1, 2, 4, 7, 14, 28 as factors
33 has 1, 3, 11, 33 as factors

Yes, you are right.
28 = 2*2*7 and 33 = 3*11.

yes you are correct because both 28 and 33 can be divided by other numbers besides 1 and itself. Prime numbers can only be divided by 1, and itself

You can reduce 28 and 33 into factors other than themselves and 1, but you cannot reduce the remaining numbers; hence, they are prime and not composite.
