To determine if 9728 is a prime number or a composite number, we simply look at the factors for 9728.
If the factors of 9728 are only 9728 and 1, then we know that 9728 is a prime number. Otherwise, 9728 is a composite number.
To explain better, if 9728 is only divisible by 1 and 9728, then it is a prime number, and if 9728 is divisible by more than 9728 and 1, then it is a composite number.
The factors of 9728 are as follows:
1, 2, 4, 8, 16, 19, 32, 38, 64, 76, 128, 152, 256, 304, 512, 608, 1216, 2432, 4864, 9728
Therefore, since 9728 is divisible by more than one and itself, the answer to the
question "Is 9728 prime or composite?" is highlighted in blue below.
