No, the numbers 19, 21, and 23 are not composite numbers. A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. In the case of these numbers, 19 and 23 are prime numbers because they are only divisible by 1 and themselves, while 21 is a composite number because it has divisors other than 1 and itself (3 and 7).

No, they are three numbers, not one. 21 is composite.
