To determine if 1422 is a prime number or a composite number, we simply look at the factors for 1422.
If the factors of 1422 are only 1422 and 1, then we know that 1422 is a prime number. Otherwise, 1422 is a composite number.
To explain better, if 1422 is only divisible by 1 and 1422, then it is a prime number, and if 1422 is divisible by more than 1422 and 1, then it is a composite number.
The factors of 1422 are as follows:
1, 2, 3, 6, 9, 18, 79, 158, 237, 474, 711, 1422
Therefore, since 1422 is divisible by more than one and itself, the answer to the
question "Is 1422 prime or composite?" is highlighted in blue below.
