To determine if 1299 is a prime number or a composite number, we simply look at the factors for 1299.
If the factors of 1299 are only 1299 and 1, then we know that 1299 is a prime number. Otherwise, 1299 is a composite number.
To explain better, if 1299 is only divisible by 1 and 1299, then it is a prime number, and if 1299 is divisible by more than 1299 and 1, then it is a composite number.
The factors of 1299 are as follows:
