To determine if 2004 is a prime number or a composite number, we simply look at the factors for 2004.
If the factors of 2004 are only 2004 and 1, then we know that 2004 is a prime number. Otherwise, 2004 is a composite number.
To explain better, if 2004 is only divisible by 1 and 2004, then it is a prime number, and if 2004 is divisible by more than 2004 and 1, then it is a composite number.
The factors of 2004 are as follows:
1, 2, 3, 4, 6, 12, 167, 334, 501, 668, 1002, 2004
Therefore, since 2004 is divisible by more than one and itself, the answer to the
question "Is 2004 prime or composite?" is highlighted in blue below.
composite
Is 2005 prime or composite?
