To determine if 2002 is a prime number or a composite number, we simply look at the factors for 2002.
If the factors of 2002 are only 2002 and 1, then we know that 2002 is a prime number. Otherwise, 2002 is a composite number.
To explain better, if 2002 is only divisible by 1 and 2002, then it is a prime number, and if 2002 is divisible by more than 2002 and 1, then it is a composite number.
The factors of 2002 are as follows:
1, 2, 7, 11, 13, 14, 22, 26, 77, 91, 143, 154, 182, 286, 1001, 2002
Therefore, since 2002 is divisible by more than one and itself, the answer to the
question "Is 2002 prime or composite?" is highlighted in blue below.
composite
Is 2003 prime or composite?
OK. Now you know that 2002 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.
