To determine if 188 is a prime number or a composite number, we simply look at the factors for 188.
If the factors of 188 are only 188 and 1, then we know that 188 is a prime number. Otherwise, 188 is a composite number.
To explain better, if 188 is only divisible by 1 and 188, then it is a prime number, and if 188 is divisible by more than 188 and 1, then it is a composite number.
The factors of 188 are as follows:
1, 2, 4, 47, 94, 188
Therefore, since 188 is divisible by more than one and itself, the answer to the
question "Is 188 prime or composite?" is highlighted in blue below.
composite
Is 189 prime or composite?
OK. Now you know that 188 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.
