To determine if 133 is a prime number or a composite number, we simply look at the factors for 133.
If the factors of 133 are only 133 and 1, then we know that 133 is a prime number. Otherwise, 133 is a composite number.
To explain better, if 133 is only divisible by 1 and 133, then it is a prime number, and if 133 is divisible by more than 133 and 1, then it is a composite number.
The factors of 133 are as follows:
1, 7, 19, 133
Therefore, since 133 is divisible by more than one and itself, the answer to the
question "Is 133 prime or composite?" is highlighted in blue below.
composite
Is 134 prime or composite?
OK. Now you know that 133 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.
