To determine if 3195 is a prime number or a composite number, we simply look at the factors for 3195.
If the factors of 3195 are only 3195 and 1, then we know that 3195 is a prime number. Otherwise, 3195 is a composite number.
To explain better, if 3195 is only divisible by 1 and 3195, then it is a prime number, and if 3195 is divisible by more than 3195 and 1, then it is a composite number.
The factors of 3195 are as follows:
1, 3, 5, 9, 15, 45, 71, 213, 355, 639, 1065, 3195
Therefore, since 3195 is divisible by more than one and itself, the answer to the
