To determine if 662 is a prime number or a composite number, we simply look at the factors for 662.
If the factors of 662 are only 662 and 1, then we know that 662 is a prime number. Otherwise, 662 is a composite number.
To explain better, if 662 is only divisible by 1 and 662, then it is a prime number, and if 662 is divisible by more than 662 and 1, then it is a composite number.
The factors of 662 are as follows:
1, 2, 331, 662
Therefore, since 662 is divisible by more than one and itself, the answer to the
question "Is 662 prime or composite?" is highlighted in blue below.
composite
Is 663 prime or composite?
