To determine if 5728 is a prime number or a composite number, we simply look at the factors for 5728.
If the factors of 5728 are only 5728 and 1, then we know that 5728 is a prime number. Otherwise, 5728 is a composite number.
To explain better, if 5728 is only divisible by 1 and 5728, then it is a prime number, and if 5728 is divisible by more than 5728 and 1, then it is a composite number.
The factors of 5728 are as follows:
1, 2, 4, 8, 16, 32, 179, 358, 716, 1432, 2864, 5728
