To determine if 2818 is a prime number or a composite number, we simply look at the factors for 2818.
If the factors of 2818 are only 2818 and 1, then we know that 2818 is a prime number. Otherwise, 2818 is a composite number.
To explain better, if 2818 is only divisible by 1 and 2818, then it is a prime number, and if 2818 is divisible by more than 2818 and 1, then it is a composite number.
The factors of 2818 are as follows:
1, 2, 1409, 2818
Therefore, since 2818 is divisible by more than one and itself, the answer to the
question "Is 2818 prime or composite?" is highlighted in blue below.
