To determine if 1141 is a prime number or a composite number, we simply look at the factors for 1141.
If the factors of 1141 are only 1141 and 1, then we know that 1141 is a prime number. Otherwise, 1141 is a composite number.
To explain better, if 1141 is only divisible by 1 and 1141, then it is a prime number, and if 1141 is divisible by more than 1141 and 1, then it is a composite number.
The factors of 1141 are as follows:
1, 7, 163, 1141
Therefore, since 1141 is divisible by more than one and itself, the answer to the
question "Is 1141 prime or composite?" is highlighted in blue below.
composite
Is 1142 prime or composite?
