To determine if 104 is a prime number or a composite number, we simply look at the factors for 104.
If the factors of 104 are only 104 and 1, then we know that 104 is a prime number. Otherwise, 104 is a composite number.
To explain better, if 104 is only divisible by 1 and 104, then it is a prime number, and if 104 is divisible by more than 104 and 1, then it is a composite number.
The factors of 104 are as follows:
1, 2, 4, 8, 13, 26, 52, 104
Therefore, since 104 is divisible by more than one and itself, the answer to the
question "Is 104 prime or composite?" is highlighted in blue below.
composite
Is 105 prime or composite?
OK. Now you know that 104 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.
