To determine if 993 is a prime number or a composite number, we simply look at the factors for 993.
If the factors of 993 are only 993 and 1, then we know that 993 is a prime number. Otherwise, 993 is a composite number.
To explain better, if 993 is only divisible by 1 and 993, then it is a prime number, and if 993 is divisible by more than 993 and 1, then it is a composite number.
The factors of 993 are as follows:
1, 3, 331, 993
Therefore, since 993 is divisible by more than one and itself, the answer to the
question "Is 993 prime or composite?" is highlighted in blue below.
composite
Is 994 prime or composite?
