To determine if 325 is a prime number or a composite number, we simply look at the factors for 325.
If the factors of 325 are only 325 and 1, then we know that 325 is a prime number. Otherwise, 325 is a composite number.
To explain better, if 325 is only divisible by 1 and 325, then it is a prime number, and if 325 is divisible by more than 325 and 1, then it is a composite number.
The factors of 325 are as follows:
1, 5, 13, 25, 65, 325
Therefore, since 325 is divisible by more than one and itself, the answer to the
question "Is 325 prime or composite?" is highlighted in blue below.
composite
Is 326 prime or composite?
OK. Now you know that 325 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.
