To determine if 1622 is a prime number or a composite number, we simply look at the factors for 1622.
If the factors of 1622 are only 1622 and 1, then we know that 1622 is a prime number. Otherwise, 1622 is a composite number.
To explain better, if 1622 is only divisible by 1 and 1622, then it is a prime number, and if 1622 is divisible by more than 1622 and 1, then it is a composite number.
The factors of 1622 are as follows:
1, 2, 811, 1622
Therefore, since 1622 is divisible by more than one and itself, the answer to the
question "Is 1622 prime or composite?" is highlighted in blue below.
composite
Is 1623 prime or composite?
