To determine if 1602 is a prime number or a composite number, we simply look at the factors for 1602.
If the factors of 1602 are only 1602 and 1, then we know that 1602 is a prime number. Otherwise, 1602 is a composite number.
To explain better, if 1602 is only divisible by 1 and 1602, then it is a prime number, and if 1602 is divisible by more than 1602 and 1, then it is a composite number.
The factors of 1602 are as follows:
1, 2, 3, 6, 9, 18, 89, 178, 267, 534, 801, 1602
Therefore, since 1602 is divisible by more than one and itself, the answer to the
question "Is 1602 prime or composite?" is highlighted in blue below.
composite
Is 1603 prime or composite?
