To determine if 1330 is a prime number or a composite number, we simply look at the factors for 1330.
If the factors of 1330 are only 1330 and 1, then we know that 1330 is a prime number. Otherwise, 1330 is a composite number.
To explain better, if 1330 is only divisible by 1 and 1330, then it is a prime number, and if 1330 is divisible by more than 1330 and 1, then it is a composite number.
The factors of 1330 are as follows:
1, 2, 5, 7, 10, 14, 19, 35, 38, 70, 95, 133, 190, 266, 665, 1330
Therefore, since 1330 is divisible by more than one and itself, the answer to the
question "Is 1330 prime or composite?" is highlighted in blue below.
composite
Is 1331 prime or composite?
OK. Now you know that 1330 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.
