To determine if 8005 is a prime number or a composite number, we simply look at the factors for 8005.
If the factors of 8005 are only 8005 and 1, then we know that 8005 is a prime number. Otherwise, 8005 is a composite number.
To explain better, if 8005 is only divisible by 1 and 8005, then it is a prime number, and if 8005 is divisible by more than 8005 and 1, then it is a composite number.
The factors of 8005 are as follows:
1, 5, 1601, 8005
Therefore, since 8005 is divisible by more than one and itself, the answer to the
question "Is 8005 prime or composite?" is highlighted in blue below.
composite
Is 8006 prime or composite?
