To determine if 249 is a prime number or a composite number, we simply look at the factors for 249.
If the factors of 249 are only 249 and 1, then we know that 249 is a prime number. Otherwise, 249 is a composite number.
To explain better, if 249 is only divisible by 1 and 249, then it is a prime number, and if 249 is divisible by more than 249 and 1, then it is a composite number.
The factors of 249 are as follows:
1, 3, 83, 249
Therefore, since 249 is divisible by more than one and itself, the answer to the
question "Is 249 prime or composite?" is highlighted in blue below.
composite
Is 250 prime or composite?
