To determine if 146 is a prime number or a composite number, we simply look at the factors for 146.
If the factors of 146 are only 146 and 1, then we know that 146 is a prime number. Otherwise, 146 is a composite number.
To explain better, if 146 is only divisible by 1 and 146, then it is a prime number, and if 146 is divisible by more than 146 and 1, then it is a composite number.
The factors of 146 are as follows:
1, 2, 73, 146
Therefore, since 146 is divisible by more than one and itself, the answer to the
question "Is 146 prime or composite?" is highlighted in blue below.
composite
Is 147 prime or composite?
OK. Now you know that 146 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.
