To determine if 131 is a prime number or a composite number, we simply look at the factors for 131.
If the factors of 131 are only 131 and 1, then we know that 131 is a prime number. Otherwise, 131 is a composite number.
To explain better, if 131 is only divisible by 1 and 131, then it is a prime number, and if 131 is divisible by more than 131 and 1, then it is a composite number.
The factors of 131 are as follows:
1, 131
Therefore, since 131 is divisible by only one and itself, the answer to the
question "Is 131 prime or composite?" is highlighted in blue below.
prime
Is 132 prime or composite?
OK. Now you know that 131 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.
