To determine if 4030 is a prime number or a composite number, we simply look at the factors for 4030.
If the factors of 4030 are only 4030 and 1, then we know that 4030 is a prime number. Otherwise, 4030 is a composite number.
To explain better, if 4030 is only divisible by 1 and 4030, then it is a prime number, and if 4030 is divisible by more than 4030 and 1, then it is a composite number.
The factors of 4030 are as follows:
1, 2, 5, 10, 13, 26, 31, 62, 65, 130, 155, 310, 403, 806, 2015, 4030
Therefore, since 4030 is divisible by more than one and itself, the answer to the
question "Is 4030 prime or composite?" is highlighted in blue below.
composite
Is 4031 prime or composite?
