To determine if 7255 is a prime number or a composite number, we simply look at the factors for 7255.
If the factors of 7255 are only 7255 and 1, then we know that 7255 is a prime number. Otherwise, 7255 is a composite number.
To explain better, if 7255 is only divisible by 1 and 7255, then it is a prime number, and if 7255 is divisible by more than 7255 and 1, then it is a composite number.
The factors of 7255 are as follows:
1, 5, 1451, 7255
Therefore, since 7255 is divisible by more than one and itself, the answer to the
question "Is 7255 prime or composite?" is highlighted in blue below.
