To determine if 1808 is a prime number or a composite number, we simply look at the factors for 1808.
If the factors of 1808 are only 1808 and 1, then we know that 1808 is a prime number. Otherwise, 1808 is a composite number.
To explain better, if 1808 is only divisible by 1 and 1808, then it is a prime number, and if 1808 is divisible by more than 1808 and 1, then it is a composite number.
The factors of 1808 are as follows:
1, 2, 4, 8, 16, 113, 226, 452, 904, 1808
Therefore, since 1808 is divisible by more than one and itself, the answer to the
question "Is 1808 prime or composite?" is highlighted in blue below.
composite
