To determine if 1606 is a prime number or a composite number, we simply look at the factors for 1606.
If the factors of 1606 are only 1606 and 1, then we know that 1606 is a prime number. Otherwise, 1606 is a composite number.
To explain better, if 1606 is only divisible by 1 and 1606, then it is a prime number, and if 1606 is divisible by more than 1606 and 1, then it is a composite number.
The factors of 1606 are as follows:
1, 2, 11, 22, 73, 146, 803, 1606
Therefore, since 1606 is divisible by more than one and itself, the answer to the
question "Is 1606 prime or composite?" is highlighted in blue below.
composite
Is 1607 prime or composite?
