To determine if 493 is a prime number or a composite number, we simply look at the factors for 493.
If the factors of 493 are only 493 and 1, then we know that 493 is a prime number. Otherwise, 493 is a composite number.
To explain better, if 493 is only divisible by 1 and 493, then it is a prime number, and if 493 is divisible by more than 493 and 1, then it is a composite number.
The factors of 493 are as follows:
1, 17, 29, 493
Therefore, since 493 is divisible by more than one and itself, the answer to the
question "Is 493 prime or composite?" is highlighted in blue below.
composite
