To determine if 130 is a prime number or a composite number, we simply look at the factors for 130.
If the factors of 130 are only 130 and 1, then we know that 130 is a prime number. Otherwise, 130 is a composite number.
To explain better, if 130 is only divisible by 1 and 130, then it is a prime number, and if 130 is divisible by more than 130 and 1, then it is a composite number.
The factors of 130 are as follows:
1, 2, 5, 10, 13, 26, 65, 130
Therefore, since 130 is divisible by more than one and itself, the answer to the
question "Is 130 prime or composite?" is highlighted in blue below.
composite
Is 131 prime or composite?
OK. Now you know that 130 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.
