To determine if 1212 is a prime number or a composite number, we simply look at the factors for 1212.
If the factors of 1212 are only 1212 and 1, then we know that 1212 is a prime number. Otherwise, 1212 is a composite number.
To explain better, if 1212 is only divisible by 1 and 1212, then it is a prime number, and if 1212 is divisible by more than 1212 and 1, then it is a composite number.
The factors of 1212 are as follows:
1, 2, 3, 4, 6, 12, 101, 202, 303, 404, 606, 1212
Therefore, since 1212 is divisible by more than one and itself, the answer to the
question "Is 1212 prime or composite?" is highlighted in blue below.
composite
Is 1213 prime or composite?
