To determine if 822 is a prime number or a composite number, we simply look at the factors for 822.
If the factors of 822 are only 822 and 1, then we know that 822 is a prime number. Otherwise, 822 is a composite number.
To explain better, if 822 is only divisible by 1 and 822, then it is a prime number, and if 822 is divisible by more than 822 and 1, then it is a composite number.
The factors of 822 are as follows:
1, 2, 3, 6, 137, 274, 411, 822
Therefore, since 822 is divisible by more than one and itself, the answer to the
question "Is 822 prime or composite?" is highlighted in blue below.
composite
Is 823 prime or composite?
