To determine if 1321 is a prime number or a composite number, we simply look at the factors for 1321.
If the factors of 1321 are only 1321 and 1, then we know that 1321 is a prime number. Otherwise, 1321 is a composite number.
To explain better, if 1321 is only divisible by 1 and 1321, then it is a prime number, and if 1321 is divisible by more than 1321 and 1, then it is a composite number.
The factors of 1321 are as follows:
