To determine if 1091 is a prime number or a composite number, we simply look at the factors for 1091.
If the factors of 1091 are only 1091 and 1, then we know that 1091 is a prime number. Otherwise, 1091 is a composite number.
To explain better, if 1091 is only divisible by 1 and 1091, then it is a prime number, and if 1091 is divisible by more than 1091 and 1, then it is a composite number.
The factors of 1091 are as follows:
1, 1091
Therefore, since 1091 is divisible by only one and itself, the answer to the
question "Is 1091 prime or composite?" is highlighted in blue below.
prime
