To determine if 2739 is a prime number or a composite number, we simply look at the factors for 2739.
If the factors of 2739 are only 2739 and 1, then we know that 2739 is a prime number. Otherwise, 2739 is a composite number.
To explain better, if 2739 is only divisible by 1 and 2739, then it is a prime number, and if 2739 is divisible by more than 2739 and 1, then it is a composite number.
The factors of 2739 are as follows:
1, 3, 11, 33, 83, 249, 913, 2739
Therefore, since 2739 is divisible by more than one and itself, the answer to the
