To determine if 415 is a prime number or a composite number, we simply look at the factors for 415.
If the factors of 415 are only 415 and 1, then we know that 415 is a prime number. Otherwise, 415 is a composite number.
To explain better, if 415 is only divisible by 1 and 415, then it is a prime number, and if 415 is divisible by more than 415 and 1, then it is a composite number.
The factors of 415 are as follows:
1, 5, 83, 415
Therefore, since 415 is divisible by more than one and itself, the answer to the
question "Is 415 prime or composite?" is highlighted in blue below.
composite
Is 416 prime or composite?
OK. Now you know that 415 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.
