To determine if 1256 is a prime number or a composite number, we simply look at the factors for 1256.
If the factors of 1256 are only 1256 and 1, then we know that 1256 is a prime number. Otherwise, 1256 is a composite number.
To explain better, if 1256 is only divisible by 1 and 1256, then it is a prime number, and if 1256 is divisible by more than 1256 and 1, then it is a composite number.
The factors of 1256 are as follows:
1, 2, 4, 8, 157, 314, 628, 1256
Therefore, since 1256 is divisible by more than one and itself, the answer to the
question "Is 1256 prime or composite?" is highlighted in blue below.
composite
Is 1257 prime or composite?
