To determine if 4023 is a prime number or a composite number, we simply look at the factors for 4023.
If the factors of 4023 are only 4023 and 1, then we know that 4023 is a prime number. Otherwise, 4023 is a composite number.
To explain better, if 4023 is only divisible by 1 and 4023, then it is a prime number, and if 4023 is divisible by more than 4023 and 1, then it is a composite number.
The factors of 4023 are as follows:
1, 3, 9, 27, 149, 447, 1341, 4023
Therefore, since 4023 is divisible by more than one and itself, the answer to the
question "Is 4023 prime or composite?" is highlighted in blue below.
