To determine if 4047 is a prime number or a composite number, we simply look at the factors for 4047.
If the factors of 4047 are only 4047 and 1, then we know that 4047 is a prime number. Otherwise, 4047 is a composite number.
To explain better, if 4047 is only divisible by 1 and 4047, then it is a prime number, and if 4047 is divisible by more than 4047 and 1, then it is a composite number.
The factors of 4047 are as follows:
1, 3, 19, 57, 71, 213, 1349, 4047
