To determine if 1273 is a prime number or a composite number, we simply look at the factors for 1273.
If the factors of 1273 are only 1273 and 1, then we know that 1273 is a prime number. Otherwise, 1273 is a composite number.
To explain better, if 1273 is only divisible by 1 and 1273, then it is a prime number, and if 1273 is divisible by more than 1273 and 1, then it is a composite number.
The factors of 1273 are as follows:
1, 19, 67, 1273
Therefore, since 1273 is divisible by more than one and itself, the answer to the
question "Is 1273 prime or composite?" is highlighted in blue below.
composite
Is 1274 prime or composite?
