To determine if 2003 is a prime number or a composite number, we simply look at the factors for 2003.
If the factors of 2003 are only 2003 and 1, then we know that 2003 is a prime number. Otherwise, 2003 is a composite number.
To explain better, if 2003 is only divisible by 1 and 2003, then it is a prime number, and if 2003 is divisible by more than 2003 and 1, then it is a composite number.
The factors of 2003 are as follows:
1, 2003
Therefore, since 2003 is divisible by only one and itself, the answer to the
question "Is 2003 prime or composite?" is highlighted in blue below.
prime
