To determine if 4155 is a prime number or a composite number, we simply look at the factors for 4155.
If the factors of 4155 are only 4155 and 1, then we know that 4155 is a prime number. Otherwise, 4155 is a composite number.
To explain better, if 4155 is only divisible by 1 and 4155, then it is a prime number, and if 4155 is divisible by more than 4155 and 1, then it is a composite number.
The factors of 4155 are as follows:
1, 3, 5, 15, 277, 831, 1385, 4155
Therefore, since 4155 is divisible by more than one and itself, the answer to the
