To determine if 2010 is a prime number or a composite number, we simply look at the factors for 2010.
If the factors of 2010 are only 2010 and 1, then we know that 2010 is a prime number. Otherwise, 2010 is a composite number.
To explain better, if 2010 is only divisible by 1 and 2010, then it is a prime number, and if 2010 is divisible by more than 2010 and 1, then it is a composite number.
The factors of 2010 are as follows:
1, 2, 3, 5, 6, 10, 15, 30, 67, 134, 201, 335, 402, 670, 1005, 2010
Therefore, since 2010 is divisible by more than one and itself, the answer to the
question "Is 2010 prime or composite?" is highlighted in blue below.
composite
Is 2011 prime or composite?
OK. Now you know that 2010 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.
