To determine if 147 is a prime number or a composite number, we simply look at the factors for 147.
If the factors of 147 are only 147 and 1, then we know that 147 is a prime number. Otherwise, 147 is a composite number.
To explain better, if 147 is only divisible by 1 and 147, then it is a prime number, and if 147 is divisible by more than 147 and 1, then it is a composite number.
The factors of 147 are as follows:
1, 3, 7, 21, 49, 147
Therefore, since 147 is divisible by more than one and itself, the answer to the
question "Is 147 prime or composite?" is highlighted in blue below.
composite
Is 148 prime or composite?
OK. Now you know that 147 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.
