To determine if 1617 is a prime number or a composite number, we simply look at the factors for 1617.
If the factors of 1617 are only 1617 and 1, then we know that 1617 is a prime number. Otherwise, 1617 is a composite number.
To explain better, if 1617 is only divisible by 1 and 1617, then it is a prime number, and if 1617 is divisible by more than 1617 and 1, then it is a composite number.
The factors of 1617 are as follows:
1, 3, 7, 11, 21, 33, 49, 77, 147, 231, 539, 1617
Therefore, since 1617 is divisible by more than one and itself, the answer to the
question "Is 1617 prime or composite?" is highlighted in blue below.
composite
Is 1618 prime or composite?
