To determine if 3509 is a prime number or a composite number, we simply look at the factors for 3509.
If the factors of 3509 are only 3509 and 1, then we know that 3509 is a prime number. Otherwise, 3509 is a composite number.
To explain better, if 3509 is only divisible by 1 and 3509, then it is a prime number, and if 3509 is divisible by more than 3509 and 1, then it is a composite number.
The factors of 3509 are as follows:
1, 11, 29, 121, 319, 3509
Therefore, since 3509 is divisible by more than one and itself, the answer to the
