To determine if 2012 is a prime number or a composite number, we simply look at the factors for 2012.
If the factors of 2012 are only 2012 and 1, then we know that 2012 is a prime number. Otherwise, 2012 is a composite number.
To explain better, if 2012 is only divisible by 1 and 2012, then it is a prime number, and if 2012 is divisible by more than 2012 and 1, then it is a composite number.
The factors of 2012 are as follows:
1, 2, 4, 503, 1006, 2012
Therefore, since 2012 is divisible by more than one and itself, the answer to the
question "Is 2012 prime or composite?" is highlighted in blue below.
composite
Is 2013 prime or composite?
OK. Now you know that 2012 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.
