To determine if 1608 is a prime number or a composite number, we simply look at the factors for 1608.
If the factors of 1608 are only 1608 and 1, then we know that 1608 is a prime number. Otherwise, 1608 is a composite number.
To explain better, if 1608 is only divisible by 1 and 1608, then it is a prime number, and if 1608 is divisible by more than 1608 and 1, then it is a composite number.
The factors of 1608 are as follows:
1, 2, 3, 4, 6, 8, 12, 24, 67, 134, 201, 268, 402, 536, 804, 1608
Therefore, since 1608 is divisible by more than one and itself, the answer to the
question "Is 1608 prime or composite?" is highlighted in blue below.
composite
Is 1609 prime or composite?
