To determine if 2001 is a prime number or a composite number, we simply look at the factors for 2001.
If the factors of 2001 are only 2001 and 1, then we know that 2001 is a prime number. Otherwise, 2001 is a composite number.
To explain better, if 2001 is only divisible by 1 and 2001, then it is a prime number, and if 2001 is divisible by more than 2001 and 1, then it is a composite number.
The factors of 2001 are as follows:
1, 3, 23, 29, 69, 87, 667, 2001
Therefore, since 2001 is divisible by more than one and itself, the answer to the
question "Is 2001 prime or composite?" is highlighted in blue below.
composite
Is 2002 prime or composite?
OK. Now you know that 2001 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
