To determine if 1055 is a prime number or a composite number, we simply look at the factors for 1055.
If the factors of 1055 are only 1055 and 1, then we know that 1055 is a prime number. Otherwise, 1055 is a composite number.
To explain better, if 1055 is only divisible by 1 and 1055, then it is a prime number, and if 1055 is divisible by more than 1055 and 1, then it is a composite number.
The factors of 1055 are as follows:
1, 5, 211, 1055
Therefore, since 1055 is divisible by more than one and itself, the answer to the
question "Is 1055 prime or composite?" is highlighted in blue below.
composite
Is 1056 prime or composite?
