To determine if 103 is a prime number or a composite number, we simply look at the factors for 103.
If the factors of 103 are only 103 and 1, then we know that 103 is a prime number. Otherwise, 103 is a composite number.
To explain better, if 103 is only divisible by 1 and 103, then it is a prime number, and if 103 is divisible by more than 103 and 1, then it is a composite number.
The factors of 103 are as follows:
1, 103
Therefore, since 103 is divisible by only one and itself, the answer to the
question "Is 103 prime or composite?" is highlighted in blue below.
prime
Is 104 prime or composite?
OK. Now you know that 103 is a prime 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.
