To determine if 2782 is a prime number or a composite number, we simply look at the factors for 2782.
If the factors of 2782 are only 2782 and 1, then we know that 2782 is a prime number. Otherwise, 2782 is a composite number.
To explain better, if 2782 is only divisible by 1 and 2782, then it is a prime number, and if 2782 is divisible by more than 2782 and 1, then it is a composite number.
The factors of 2782 are as follows:
1, 2, 13, 26, 107, 214, 1391, 2782
Therefore, since 2782 is divisible by more than one and itself, the answer to the
