To determine if 247 is a prime number or a composite number, we simply look at the factors for 247.
If the factors of 247 are only 247 and 1, then we know that 247 is a prime number. Otherwise, 247 is a composite number.
To explain better, if 247 is only divisible by 1 and 247, then it is a prime number, and if 247 is divisible by more than 247 and 1, then it is a composite number.
The factors of 247 are as follows:
1, 13, 19, 247
Therefore, since 247 is divisible by more than one and itself, the answer to the
question "Is 247 prime or composite?" is highlighted in blue below.
composite
Is 248 prime or composite?
OK. Now you know that 247 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
