To determine if 8019 is a prime number or a composite number, we simply look at the factors for 8019.
If the factors of 8019 are only 8019 and 1, then we know that 8019 is a prime number. Otherwise, 8019 is a composite number.
To explain better, if 8019 is only divisible by 1 and 8019, then it is a prime number, and if 8019 is divisible by more than 8019 and 1, then it is a composite number.
The factors of 8019 are as follows:
1, 3, 9, 11, 27, 33, 81, 99, 243, 297, 729, 891, 2673, 8019
Therefore, since 8019 is divisible by more than one and itself, the answer to the
question "Is 8019 prime or composite?" is highlighted in blue below.
composite
Is 8020 prime or composite?
