To determine if 1646 is a prime number or a composite number, we simply look at the factors for 1646.
If the factors of 1646 are only 1646 and 1, then we know that 1646 is a prime number. Otherwise, 1646 is a composite number.
To explain better, if 1646 is only divisible by 1 and 1646, then it is a prime number, and if 1646 is divisible by more than 1646 and 1, then it is a composite number.
The factors of 1646 are as follows:
