To determine if 259 is a prime number or a composite number, we simply look at the factors for 259.
If the factors of 259 are only 259 and 1, then we know that 259 is a prime number. Otherwise, 259 is a composite number.
To explain better, if 259 is only divisible by 1 and 259, then it is a prime number, and if 259 is divisible by more than 259 and 1, then it is a composite number.
The factors of 259 are as follows:
1, 7, 37, 259
Therefore, since 259 is divisible by more than one and itself, the answer to the
question "Is 259 prime or composite?" is highlighted in blue below.
composite
Is 260 prime or composite?
OK. Now you know that 259 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.
