To determine if 2008 is a prime number or a composite number, we simply look at the factors for 2008.
If the factors of 2008 are only 2008 and 1, then we know that 2008 is a prime number. Otherwise, 2008 is a composite number.
To explain better, if 2008 is only divisible by 1 and 2008, then it is a prime number, and if 2008 is divisible by more than 2008 and 1, then it is a composite number.
The factors of 2008 are as follows:
1, 2, 4, 8, 251, 502, 1004, 2008
Therefore, since 2008 is divisible by more than one and itself, the answer to the
question "Is 2008 prime or composite?" is highlighted in blue below.
composite
Is 2009 prime or composite?
