To determine if 1001 is a prime number or a composite number, we simply look at the factors for 1001.
If the factors of 1001 are only 1001 and 1, then we know that 1001 is a prime number. Otherwise, 1001 is a composite number.
To explain better, if 1001 is only divisible by 1 and 1001, then it is a prime number, and if 1001 is divisible by more than 1001 and 1, then it is a composite number.
The factors of 1001 are as follows:
1, 7, 11, 13, 77, 91, 143, 1001
Therefore, since 1001 is divisible by more than one and itself, the answer to the
question "Is 1001 prime or composite?" is highlighted in blue below.
composite
Is 1002 prime or composite?
OK. Now you know that 1001 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.
