To determine if 911 is a prime number or a composite number, we simply look at the factors for 911.
If the factors of 911 are only 911 and 1, then we know that 911 is a prime number. Otherwise, 911 is a composite number.
To explain better, if 911 is only divisible by 1 and 911, then it is a prime number, and if 911 is divisible by more than 911 and 1, then it is a composite number.
The factors of 911 are as follows:
1, 911
Therefore, since 911 is divisible by only one and itself, the answer to the
question "Is 911 prime or composite?" is highlighted in blue below.
prime
Is 912 prime or composite?
