To determine if 2007 is a prime number or a composite number, we simply look at the factors for 2007.
If the factors of 2007 are only 2007 and 1, then we know that 2007 is a prime number. Otherwise, 2007 is a composite number.
To explain better, if 2007 is only divisible by 1 and 2007, then it is a prime number, and if 2007 is divisible by more than 2007 and 1, then it is a composite number.
The factors of 2007 are as follows:
1, 3, 9, 223, 669, 2007
Therefore, since 2007 is divisible by more than one and itself, the answer to the
question "Is 2007 prime or composite?" is highlighted in blue below.
composite
Is 2008 prime or composite?
