The composite numbers from 2 to 20 are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, and 20.
The composite numbers between 1000 and 1005 are numbers that have factors other than 1 and themselves. In this range, the numbers 1001, 1002, 1003, and 1004 are composite numbers. 1000 is not a composite number because it is divisible by 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500, and 1000.
21 and 22.
The set of even numbers contains the prime number, 2. The set of composite numbers contains infinitely many odd numbers.
All even numbers are composite, because 2 is a factor of every even number.
The composite numbers from 2 to 20 are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, and 20.

no, 20 is even; therefore it is a multiple of 2.
21 and 22.
9 and 15 are the only two odd composite numbers less than twenty.
Twenty is composite. It has the factors 1, 2, 4 ,5, 10, and 20. Prime numbers have exactly two factors. Composite numbers have three or more.
10 and 20 are composite numbers, not prime numbers. The prime factorization of 10 is 2 x 5. The prime factorization of 20 is 2 x 2 x 5.
The set of even numbers contains the prime number, 2. The set of composite numbers contains infinitely many odd numbers.
All even numbers are composite, because 2 is a factor of every even number.
