To determine if 411 is a prime number or a composite number, we simply look at the factors for 411.
If the factors of 411 are only 411 and 1, then we know that 411 is a prime number. Otherwise, 411 is a composite number.
To explain better, if 411 is only divisible by 1 and 411, then it is a prime number, and if 411 is divisible by more than 411 and 1, then it is a composite number.
The factors of 411 are as follows:
1, 3, 137, 411
Therefore, since 411 is divisible by more than one and itself, the answer to the
question "Is 411 prime or composite?" is highlighted in blue below.
composite
Is 412 prime or composite?
OK. Now you know that 411 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.
