To determine if 1254 is a prime number or a composite number, we simply look at the factors for 1254.
If the factors of 1254 are only 1254 and 1, then we know that 1254 is a prime number. Otherwise, 1254 is a composite number.
To explain better, if 1254 is only divisible by 1 and 1254, then it is a prime number, and if 1254 is divisible by more than 1254 and 1, then it is a composite number.
The factors of 1254 are as follows:
1, 2, 3, 6, 11, 19, 22, 33, 38, 57, 66, 114, 209, 418, 627, 1254
Therefore, since 1254 is divisible by more than one and itself, the answer to the
question "Is 1254 prime or composite?" is highlighted in blue below.
composite
Is 1255 prime or composite?
