To determine if 828 is a prime number or a composite number, we simply look at the factors for 828.
If the factors of 828 are only 828 and 1, then we know that 828 is a prime number. Otherwise, 828 is a composite number.
To explain better, if 828 is only divisible by 1 and 828, then it is a prime number, and if 828 is divisible by more than 828 and 1, then it is a composite number.
The factors of 828 are as follows:
1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
Therefore, since 828 is divisible by more than one and itself, the answer to the
question "Is 828 prime or composite?" is highlighted in blue below.
composite
Is 829 prime or composite?
OK. Now you know that 828 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.
