To determine if 1569 is a prime number or a composite number, we simply look at the factors for 1569.
If the factors of 1569 are only 1569 and 1, then we know that 1569 is a prime number. Otherwise, 1569 is a composite number.
To explain better, if 1569 is only divisible by 1 and 1569, then it is a prime number, and if 1569 is divisible by more than 1569 and 1, then it is a composite number.
The factors of 1569 are as follows:
