To determine if 3115 is a prime number or a composite number, we simply look at the factors for 3115.
If the factors of 3115 are only 3115 and 1, then we know that 3115 is a prime number. Otherwise, 3115 is a composite number.
To explain better, if 3115 is only divisible by 1 and 3115, then it is a prime number, and if 3115 is divisible by more than 3115 and 1, then it is a composite number.
The factors of 3115 are as follows:
1, 5, 7, 35, 89, 445, 623, 3115
Therefore, since 3115 is divisible by more than one and itself, the answer to the
question "Is 3115 prime or composite?" is highlighted in blue below.
