To determine if 1393 is a prime number or a composite number, we simply look at the factors for 1393.
If the factors of 1393 are only 1393 and 1, then we know that 1393 is a prime number. Otherwise, 1393 is a composite number.
To explain better, if 1393 is only divisible by 1 and 1393, then it is a prime number, and if 1393 is divisible by more than 1393 and 1, then it is a composite number.
The factors of 1393 are as follows:
1, 7, 199, 1393
Therefore, since 1393 is divisible by more than one and itself, the answer to the
question "Is 1393 prime or composite?" is highlighted in blue below.
