They are: 12 14 15 16 18 and 20 because they all have more than two factors
The composite numbers up to 20 are 4,6,8,9,12,14,15,16,18 and 20.
12, 14, 15, 16 and 18.
15 is a composite number - it can be divided by 3 and 5. 11, 13, 17 and 19 are all prime numbers, not composite.
Not all numbers between 20 and 28 are composite numbers. 23 is a prime number.
None of the numbers 7, 11, and 13 are composite numbers; they are all primes.

Well, honey, composite numbers are those divas that have more than two divisors, so the first 11 composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, and 20. They may not be prime, but they sure know how to party with all those divisors.
None of the numbers 7, 11, and 13 are composite numbers; they are all primes.
