To determine if 152 is a prime number or a composite number, we simply look at the factors for 152.
If the factors of 152 are only 152 and 1, then we know that 152 is a prime number. Otherwise, 152 is a composite number.
To explain better, if 152 is only divisible by 1 and 152, then it is a prime number, and if 152 is divisible by more than 152 and 1, then it is a composite number.
The factors of 152 are as follows:
1, 2, 4, 8, 19, 38, 76, 152
Therefore, since 152 is divisible by more than one and itself, the answer to the
question "Is 152 prime or composite?" is highlighted in blue below.
composite
Is 153 prime or composite?
OK. Now you know that 152 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.
