To determine if 1010 is a prime number or a composite number, we simply look at the factors for 1010.
If the factors of 1010 are only 1010 and 1, then we know that 1010 is a prime number. Otherwise, 1010 is a composite number.
To explain better, if 1010 is only divisible by 1 and 1010, then it is a prime number, and if 1010 is divisible by more than 1010 and 1, then it is a composite number.
The factors of 1010 are as follows:
1, 2, 5, 10, 101, 202, 505, 1010
Therefore, since 1010 is divisible by more than one and itself, the answer to the
question "Is 1010 prime or composite?" is highlighted in blue below.
composite
Is 1011 prime or composite?
OK. Now you know that 1010 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.
