To determine if 5155 is a prime number or a composite number, we simply look at the factors for 5155.
If the factors of 5155 are only 5155 and 1, then we know that 5155 is a prime number. Otherwise, 5155 is a composite number.
To explain better, if 5155 is only divisible by 1 and 5155, then it is a prime number, and if 5155 is divisible by more than 5155 and 1, then it is a composite number.
The factors of 5155 are as follows:
