To determine if 1015 is a prime number or a composite number, we simply look at the factors for 1015.
If the factors of 1015 are only 1015 and 1, then we know that 1015 is a prime number. Otherwise, 1015 is a composite number.
To explain better, if 1015 is only divisible by 1 and 1015, then it is a prime number, and if 1015 is divisible by more than 1015 and 1, then it is a composite number.
The factors of 1015 are as follows:
1, 5, 7, 29, 35, 145, 203, 1015
Therefore, since 1015 is divisible by more than one and itself, the answer to the
question "Is 1015 prime or composite?" is highlighted in blue below.
composite
Is 1016 prime or composite?
OK. Now you know that 1015 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.
