To determine if 841 is a prime number or a composite number, we simply look at the factors for 841.
If the factors of 841 are only 841 and 1, then we know that 841 is a prime number. Otherwise, 841 is a composite number.
To explain better, if 841 is only divisible by 1 and 841, then it is a prime number, and if 841 is divisible by more than 841 and 1, then it is a composite number.
The factors of 841 are as follows:
1, 29, 841
Therefore, since 841 is divisible by more than one and itself, the answer to the
question "Is 841 prime or composite?" is highlighted in blue below.
composite
Is 842 prime or composite?
OK. Now you know that 841 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.
