To determine if 136 is a prime number or a composite number, we simply look at the factors for 136.
If the factors of 136 are only 136 and 1, then we know that 136 is a prime number. Otherwise, 136 is a composite number.
To explain better, if 136 is only divisible by 1 and 136, then it is a prime number, and if 136 is divisible by more than 136 and 1, then it is a composite number.
The factors of 136 are as follows:
1, 2, 4, 8, 17, 34, 68, 136
Therefore, since 136 is divisible by more than one and itself, the answer to the
question "Is 136 prime or composite?" is highlighted in blue below.
composite
Is 137 prime or composite?
OK. Now you know that 136 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.
