To determine if 1028 is a prime number or a composite number, we simply look at the factors for 1028.
If the factors of 1028 are only 1028 and 1, then we know that 1028 is a prime number. Otherwise, 1028 is a composite number.
To explain better, if 1028 is only divisible by 1 and 1028, then it is a prime number, and if 1028 is divisible by more than 1028 and 1, then it is a composite number.
The factors of 1028 are as follows:
1, 2, 4, 257, 514, 1028
Therefore, since 1028 is divisible by more than one and itself, the answer to the
question "Is 1028 prime or composite?" is highlighted in blue below.
composite
Is 1029 prime or composite?
