To determine if 4280 is a prime number or a composite number, we simply look at the factors for 4280.
If the factors of 4280 are only 4280 and 1, then we know that 4280 is a prime number. Otherwise, 4280 is a composite number.
To explain better, if 4280 is only divisible by 1 and 4280, then it is a prime number, and if 4280 is divisible by more than 4280 and 1, then it is a composite number.
The factors of 4280 are as follows:
1, 2, 4, 5, 8, 10, 20, 40, 107, 214, 428, 535, 856, 1070, 2140, 4280
Therefore, since 4280 is divisible by more than one and itself, the answer to the
question "Is 4280 prime or composite?" is highlighted in blue below.
composite
Is 4281 prime or composite?
