To determine if 1804 is a prime number or a composite number, we simply look at the factors for 1804.
If the factors of 1804 are only 1804 and 1, then we know that 1804 is a prime number. Otherwise, 1804 is a composite number.
To explain better, if 1804 is only divisible by 1 and 1804, then it is a prime number, and if 1804 is divisible by more than 1804 and 1, then it is a composite number.
The factors of 1804 are as follows:
1, 2, 4, 11, 22, 41, 44, 82, 164, 451, 902, 1804
Therefore, since 1804 is divisible by more than one and itself, the answer to the
question "Is 1804 prime or composite?" is highlighted in blue below.
composite
Is 1805 prime or composite?
