To determine if 2013 is a prime number or a composite number, we simply look at the factors for 2013.
If the factors of 2013 are only 2013 and 1, then we know that 2013 is a prime number. Otherwise, 2013 is a composite number.
To explain better, if 2013 is only divisible by 1 and 2013, then it is a prime number, and if 2013 is divisible by more than 2013 and 1, then it is a composite number.
The factors of 2013 are as follows:
1, 3, 11, 33, 61, 183, 671, 2013
Therefore, since 2013 is divisible by more than one and itself, the answer to the
question "Is 2013 prime or composite?" is highlighted in blue below.
composite
Is 2014 prime or composite?
OK. Now you know that 2013 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.
