To determine if 1003 is a prime number or a composite number, we simply look at the factors for 1003.
If the factors of 1003 are only 1003 and 1, then we know that 1003 is a prime number. Otherwise, 1003 is a composite number.
To explain better, if 1003 is only divisible by 1 and 1003, then it is a prime number, and if 1003 is divisible by more than 1003 and 1, then it is a composite number.
The factors of 1003 are as follows:
1, 17, 59, 1003
Therefore, since 1003 is divisible by more than one and itself, the answer to the
question "Is 1003 prime or composite?" is highlighted in blue below.
composite
Is 1004 prime or composite?
OK. Now you know that 1003 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.
