To determine if 230 is a prime number or a composite number, we simply look at the factors for 230.
If the factors of 230 are only 230 and 1, then we know that 230 is a prime number. Otherwise, 230 is a composite number.
To explain better, if 230 is only divisible by 1 and 230, then it is a prime number, and if 230 is divisible by more than 230 and 1, then it is a composite number.
The factors of 230 are as follows:
1, 2, 5, 10, 23, 46, 115, 230
Therefore, since 230 is divisible by more than one and itself, the answer to the
question "Is 230 prime or composite?" is highlighted in blue below.
composite
Is 231 prime or composite?
OK. Now you know that 230 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.
