To determine if 654 is a prime number or a composite number, we simply look at the factors for 654.
If the factors of 654 are only 654 and 1, then we know that 654 is a prime number. Otherwise, 654 is a composite number.
To explain better, if 654 is only divisible by 1 and 654, then it is a prime number, and if 654 is divisible by more than 654 and 1, then it is a composite number.
The factors of 654 are as follows:
1, 2, 3, 6, 109, 218, 327, 654
Therefore, since 654 is divisible by more than one and itself, the answer to the
question "Is 654 prime or composite?" is highlighted in blue below.
composite
Is 655 prime or composite?
