To determine if 1510 is a prime number or a composite number, we simply look at the factors for 1510.
If the factors of 1510 are only 1510 and 1, then we know that 1510 is a prime number. Otherwise, 1510 is a composite number.
To explain better, if 1510 is only divisible by 1 and 1510, then it is a prime number, and if 1510 is divisible by more than 1510 and 1, then it is a composite number.
The factors of 1510 are as follows:
1, 2, 5, 10, 151, 302, 755, 1510
Therefore, since 1510 is divisible by more than one and itself, the answer to the
question "Is 1510 prime or composite?" is highlighted in blue below.
composite
Is 1511 prime or composite?
OK. Now you know that 1510 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.
