To determine if 1219 is a prime number or a composite number, we simply look at the factors for 1219.
If the factors of 1219 are only 1219 and 1, then we know that 1219 is a prime number. Otherwise, 1219 is a composite number.
To explain better, if 1219 is only divisible by 1 and 1219, then it is a prime number, and if 1219 is divisible by more than 1219 and 1, then it is a composite number.
The factors of 1219 are as follows:
1, 23, 53, 1219
Therefore, since 1219 is divisible by more than one and itself, the answer to the
question "Is 1219 prime or composite?" is highlighted in blue below.
composite
Is 1220 prime or composite?
