To determine if 1227 is a prime number or a composite number, we simply look at the factors for 1227.
If the factors of 1227 are only 1227 and 1, then we know that 1227 is a prime number. Otherwise, 1227 is a composite number.
To explain better, if 1227 is only divisible by 1 and 1227, then it is a prime number, and if 1227 is divisible by more than 1227 and 1, then it is a composite number.
The factors of 1227 are as follows:
1, 3, 409, 1227
Therefore, since 1227 is divisible by more than one and itself, the answer to the
question "Is 1227 prime or composite?" is highlighted in blue below.
composite
Is 1228 prime or composite?
