To determine if 801 is a prime number or a composite number, we simply look at the factors for 801.
If the factors of 801 are only 801 and 1, then we know that 801 is a prime number. Otherwise, 801 is a composite number.
To explain better, if 801 is only divisible by 1 and 801, then it is a prime number, and if 801 is divisible by more than 801 and 1, then it is a composite number.
The factors of 801 are as follows:
1, 3, 9, 89, 267, 801
Therefore, since 801 is divisible by more than one and itself, the answer to the
question "Is 801 prime or composite?" is highlighted in blue below.
composite
Is 802 prime or composite?
OK. Now you know that 801 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.
