To determine if 2842 is a prime number or a composite number, we simply look at the factors for 2842.
If the factors of 2842 are only 2842 and 1, then we know that 2842 is a prime number. Otherwise, 2842 is a composite number.
To explain better, if 2842 is only divisible by 1 and 2842, then it is a prime number, and if 2842 is divisible by more than 2842 and 1, then it is a composite number.
The factors of 2842 are as follows:
1, 2, 7, 14, 29, 49, 58, 98, 203, 406, 1421, 2842
Therefore, since 2842 is divisible by more than one and itself, the answer to the
question "Is 2842 prime or composite?" is highlighted in blue below.
