To determine if 1816 is a prime number or a composite number, we simply look at the factors for 1816.
If the factors of 1816 are only 1816 and 1, then we know that 1816 is a prime number. Otherwise, 1816 is a composite number.
To explain better, if 1816 is only divisible by 1 and 1816, then it is a prime number, and if 1816 is divisible by more than 1816 and 1, then it is a composite number.
The factors of 1816 are as follows:
1, 2, 4, 8, 227, 454, 908, 1816
Therefore, since 1816 is divisible by more than one and itself, the answer to the
question "Is 1816 prime or composite?" is highlighted in blue below.
composite
Is 1817 prime or composite?
