To determine if 1662 is a prime number or a composite number, we simply look at the factors for 1662.
If the factors of 1662 are only 1662 and 1, then we know that 1662 is a prime number. Otherwise, 1662 is a composite number.
To explain better, if 1662 is only divisible by 1 and 1662, then it is a prime number, and if 1662 is divisible by more than 1662 and 1, then it is a composite number.
The factors of 1662 are as follows:
1, 2, 3, 6, 277, 554, 831, 1662
Therefore, since 1662 is divisible by more than one and itself, the answer to the
question "Is 1662 prime or composite?" is highlighted in blue below.
