To determine if 2728 is a prime number or a composite number, we simply look at the factors for 2728.
If the factors of 2728 are only 2728 and 1, then we know that 2728 is a prime number. Otherwise, 2728 is a composite number.
To explain better, if 2728 is only divisible by 1 and 2728, then it is a prime number, and if 2728 is divisible by more than 2728 and 1, then it is a composite number.
The factors of 2728 are as follows:
1, 2, 4, 8, 11, 22, 31, 44, 62, 88, 124, 248, 341, 682, 1364, 2728
Therefore, since 2728 is divisible by more than one and itself, the answer to the
question "Is 2728 prime or composite?" is highlighted in blue below.
