To determine if 1004 is a prime number or a composite number, we simply look at the factors for 1004.
If the factors of 1004 are only 1004 and 1, then we know that 1004 is a prime number. Otherwise, 1004 is a composite number.
To explain better, if 1004 is only divisible by 1 and 1004, then it is a prime number, and if 1004 is divisible by more than 1004 and 1, then it is a composite number.
The factors of 1004 are as follows:
1, 2, 4, 251, 502, 1004
Therefore, since 1004 is divisible by more than one and itself, the answer to the
question "Is 1004 prime or composite?" is highlighted in blue below.
composite
Is 1005 prime or composite?
OK. Now you know that 1004 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.
