To determine if 2409 is a prime number or a composite number, we simply look at the factors for 2409.
If the factors of 2409 are only 2409 and 1, then we know that 2409 is a prime number. Otherwise, 2409 is a composite number.
To explain better, if 2409 is only divisible by 1 and 2409, then it is a prime number, and if 2409 is divisible by more than 2409 and 1, then it is a composite number.
The factors of 2409 are as follows:
1, 3, 11, 33, 73, 219, 803, 2409
Therefore, since 2409 is divisible by more than one and itself, the answer to the
question "Is 2409 prime or composite?" is highlighted in blue below.
