To determine if 9005 is a prime number or a composite number, we simply look at the factors for 9005.
If the factors of 9005 are only 9005 and 1, then we know that 9005 is a prime number. Otherwise, 9005 is a composite number.
To explain better, if 9005 is only divisible by 1 and 9005, then it is a prime number, and if 9005 is divisible by more than 9005 and 1, then it is a composite number.
The factors of 9005 are as follows:
1, 5, 1801, 9005
Therefore, since 9005 is divisible by more than one and itself, the answer to the
question "Is 9005 prime or composite?" is highlighted in blue below.
composite
Is 9006 prime or composite?
