To determine if 1618 is a prime number or a composite number, we simply look at the factors for 1618.
If the factors of 1618 are only 1618 and 1, then we know that 1618 is a prime number. Otherwise, 1618 is a composite number.
To explain better, if 1618 is only divisible by 1 and 1618, then it is a prime number, and if 1618 is divisible by more than 1618 and 1, then it is a composite number.
The factors of 1618 are as follows:
1, 2, 809, 1618
Therefore, since 1618 is divisible by more than one and itself, the answer to the
question "Is 1618 prime or composite?" is highlighted in blue below.
composite
Is 1619 prime or composite?
