To determine if 804 is a prime number or a composite number, we simply look at the factors for 804.
If the factors of 804 are only 804 and 1, then we know that 804 is a prime number. Otherwise, 804 is a composite number.
To explain better, if 804 is only divisible by 1 and 804, then it is a prime number, and if 804 is divisible by more than 804 and 1, then it is a composite number.
The factors of 804 are as follows:
1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
Therefore, since 804 is divisible by more than one and itself, the answer to the
question "Is 804 prime or composite?" is highlighted in blue below.
composite
Is 805 prime or composite?
