To determine if 1222 is a prime number or a composite number, we simply look at the factors for 1222.
If the factors of 1222 are only 1222 and 1, then we know that 1222 is a prime number. Otherwise, 1222 is a composite number.
To explain better, if 1222 is only divisible by 1 and 1222, then it is a prime number, and if 1222 is divisible by more than 1222 and 1, then it is a composite number.
The factors of 1222 are as follows:
1, 2, 13, 26, 47, 94, 611, 1222
Therefore, since 1222 is divisible by more than one and itself, the answer to the
question "Is 1222 prime or composite?" is highlighted in blue below.
composite
Is 1223 prime or composite?
