To determine if 1021 is a prime number or a composite number, we simply look at the factors for 1021.
If the factors of 1021 are only 1021 and 1, then we know that 1021 is a prime number. Otherwise, 1021 is a composite number.
To explain better, if 1021 is only divisible by 1 and 1021, then it is a prime number, and if 1021 is divisible by more than 1021 and 1, then it is a composite number.
The factors of 1021 are as follows:
1, 1021
Therefore, since 1021 is divisible by only one and itself, the answer to the
question "Is 1021 prime or composite?" is highlighted in blue below.
prime
Is 1022 prime or composite?
OK. Now you know that 1021 is a prime 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.
