To determine if 1822 is a prime number or a composite number, we simply look at the factors for 1822.
If the factors of 1822 are only 1822 and 1, then we know that 1822 is a prime number. Otherwise, 1822 is a composite number.
To explain better, if 1822 is only divisible by 1 and 1822, then it is a prime number, and if 1822 is divisible by more than 1822 and 1, then it is a composite number.
The factors of 1822 are as follows:
1, 2, 911, 1822
Therefore, since 1822 is divisible by more than one and itself, the answer to the
question "Is 1822 prime or composite?" is highlighted in blue below.
composite
Is 1823 prime or composite?
