To determine if 812 is a prime number or a composite number, we simply look at the factors for 812.
If the factors of 812 are only 812 and 1, then we know that 812 is a prime number. Otherwise, 812 is a composite number.
To explain better, if 812 is only divisible by 1 and 812, then it is a prime number, and if 812 is divisible by more than 812 and 1, then it is a composite number.
The factors of 812 are as follows:
1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
Therefore, since 812 is divisible by more than one and itself, the answer to the
question "Is 812 prime or composite?" is highlighted in blue below.
composite
Is 813 prime or composite?
OK. Now you know that 812 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.
