To determine if 1115 is a prime number or a composite number, we simply look at the factors for 1115.
If the factors of 1115 are only 1115 and 1, then we know that 1115 is a prime number. Otherwise, 1115 is a composite number.
To explain better, if 1115 is only divisible by 1 and 1115, then it is a prime number, and if 1115 is divisible by more than 1115 and 1, then it is a composite number.
The factors of 1115 are as follows:
1, 5, 223, 1115
Therefore, since 1115 is divisible by more than one and itself, the answer to the
question "Is 1115 prime or composite?" is highlighted in blue below.
composite
Is 1116 prime or composite?
