To determine if 208 is a prime number or a composite number, we simply look at the factors for 208.
If the factors of 208 are only 208 and 1, then we know that 208 is a prime number. Otherwise, 208 is a composite number.
To explain better, if 208 is only divisible by 1 and 208, then it is a prime number, and if 208 is divisible by more than 208 and 1, then it is a composite number.
The factors of 208 are as follows:
1, 2, 4, 8, 13, 16, 26, 52, 104, 208
Therefore, since 208 is divisible by more than one and itself, the answer to the
question "Is 208 prime or composite?" is highlighted in blue below.
composite
Is 209 prime or composite?
OK. Now you know that 208 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.
