To determine if 1611 is a prime number or a composite number, we simply look at the factors for 1611.
If the factors of 1611 are only 1611 and 1, then we know that 1611 is a prime number. Otherwise, 1611 is a composite number.
To explain better, if 1611 is only divisible by 1 and 1611, then it is a prime number, and if 1611 is divisible by more than 1611 and 1, then it is a composite number.
The factors of 1611 are as follows:
1, 3, 9, 179, 537, 1611
Therefore, since 1611 is divisible by more than one and itself, the answer to the
question "Is 1611 prime or composite?" is highlighted in blue below.
composite
Is 1612 prime or composite?
