To determine if 3055 is a prime number or a composite number, we simply look at the factors for 3055.
If the factors of 3055 are only 3055 and 1, then we know that 3055 is a prime number. Otherwise, 3055 is a composite number.
To explain better, if 3055 is only divisible by 1 and 3055, then it is a prime number, and if 3055 is divisible by more than 3055 and 1, then it is a composite number.
The factors of 3055 are as follows:
1, 5, 13, 47, 65, 235, 611, 3055
Therefore, since 3055 is divisible by more than one and itself, the answer to the
question "Is 3055 prime or composite?" is highlighted in blue below.
composite
