To determine if 1057 is a prime number or a composite number, we simply look at the factors for 1057.
If the factors of 1057 are only 1057 and 1, then we know that 1057 is a prime number. Otherwise, 1057 is a composite number.
To explain better, if 1057 is only divisible by 1 and 1057, then it is a prime number, and if 1057 is divisible by more than 1057 and 1, then it is a composite number.
The factors of 1057 are as follows:
1, 7, 151, 1057
Therefore, since 1057 is divisible by more than one and itself, the answer to the
question "Is 1057 prime or composite?" is highlighted in blue below.
composite
Is 1058 prime or composite?
