To determine if 195 is a prime number or a composite number, we simply look at the factors for 195.
If the factors of 195 are only 195 and 1, then we know that 195 is a prime number. Otherwise, 195 is a composite number.
To explain better, if 195 is only divisible by 1 and 195, then it is a prime number, and if 195 is divisible by more than 195 and 1, then it is a composite number.
The factors of 195 are as follows:
1, 3, 5, 13, 15, 39, 65, 195
Therefore, since 195 is divisible by more than one and itself, the answer to the
question "Is 195 prime or composite?" is highlighted in blue below.
composite
Is 196 prime or composite?
OK. Now you know that 195 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.
