To determine if 2858 is a prime number or a composite number, we simply look at the factors for 2858.
If the factors of 2858 are only 2858 and 1, then we know that 2858 is a prime number. Otherwise, 2858 is a composite number.
To explain better, if 2858 is only divisible by 1 and 2858, then it is a prime number, and if 2858 is divisible by more than 2858 and 1, then it is a composite number.
The factors of 2858 are as follows:
