To determine if 4240 is a prime number or a composite number, we simply look at the factors for 4240.
If the factors of 4240 are only 4240 and 1, then we know that 4240 is a prime number. Otherwise, 4240 is a composite number.
To explain better, if 4240 is only divisible by 1 and 4240, then it is a prime number, and if 4240 is divisible by more than 4240 and 1, then it is a composite number.
The factors of 4240 are as follows:
1, 2, 4, 5, 8, 10, 16, 20, 40, 53, 80, 106, 212, 265, 424, 530, 848, 1060, 2120, 4240
Therefore, since 4240 is divisible by more than one and itself, the answer to the
question "Is 4240 prime or composite?" is highlighted in blue below.
composite
Is 4241 prime or composite?
