To determine if 5005 is a prime number or a composite number, we simply look at the factors for 5005.
If the factors of 5005 are only 5005 and 1, then we know that 5005 is a prime number. Otherwise, 5005 is a composite number.
To explain better, if 5005 is only divisible by 1 and 5005, then it is a prime number, and if 5005 is divisible by more than 5005 and 1, then it is a composite number.
The factors of 5005 are as follows:
1, 5, 7, 11, 13, 35, 55, 65, 77, 91, 143, 385, 455, 715, 1001, 5005
Therefore, since 5005 is divisible by more than one and itself, the answer to the
question "Is 5005 prime or composite?" is highlighted in blue below.
composite
Is 5006 prime or composite?
