To determine if 2812 is a prime number or a composite number, we simply look at the factors for 2812.
If the factors of 2812 are only 2812 and 1, then we know that 2812 is a prime number. Otherwise, 2812 is a composite number.
To explain better, if 2812 is only divisible by 1 and 2812, then it is a prime number, and if 2812 is divisible by more than 2812 and 1, then it is a composite number.
The factors of 2812 are as follows:
1, 2, 4, 19, 37, 38, 74, 76, 148, 703, 1406, 2812
Therefore, since 2812 is divisible by more than one and itself, the answer to the
question "Is 2812 prime or composite?" is highlighted in blue below.
composite
Is 2813 prime or composite?
