To determine if 82 is a prime number or a composite number, we simply look at the factors for 82.
If the factors of 82 are only 82 and 1, then we know that 82 is a prime number. Otherwise, 82 is a composite number.
To explain better, if 82 is only divisible by 1 and 82, then it is a prime number, and if 82 is divisible by more than 82 and 1, then it is a composite number.
The factors of 82 are as follows:
1, 2, 41, 82
Therefore, since 82 is divisible by more than one and itself, the answer to the
question "Is 82 prime or composite?" is highlighted in blue below.
composite
Is 83 prime or composite?
OK. Now you know that 82 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.
