To determine if 1121 is a prime number or a composite number, we simply look at the factors for 1121.
If the factors of 1121 are only 1121 and 1, then we know that 1121 is a prime number. Otherwise, 1121 is a composite number.
To explain better, if 1121 is only divisible by 1 and 1121, then it is a prime number, and if 1121 is divisible by more than 1121 and 1, then it is a composite number.
The factors of 1121 are as follows:
1, 19, 59, 1121
Therefore, since 1121 is divisible by more than one and itself, the answer to the
question "Is 1121 prime or composite?" is highlighted in blue below.
composite
Is 1122 prime or composite?
