To determine if 4255 is a prime number or a composite number, we simply look at the factors for 4255.
If the factors of 4255 are only 4255 and 1, then we know that 4255 is a prime number. Otherwise, 4255 is a composite number.
To explain better, if 4255 is only divisible by 1 and 4255, then it is a prime number, and if 4255 is divisible by more than 4255 and 1, then it is a composite number.
The factors of 4255 are as follows:
1, 5, 23, 37, 115, 185, 851, 4255
Therefore, since 4255 is divisible by more than one and itself, the answer to the
question "Is 4255 prime or composite?" is highlighted in blue below.
