To determine if 4070 is a prime number or a composite number, we simply look at the factors for 4070.
If the factors of 4070 are only 4070 and 1, then we know that 4070 is a prime number. Otherwise, 4070 is a composite number.
To explain better, if 4070 is only divisible by 1 and 4070, then it is a prime number, and if 4070 is divisible by more than 4070 and 1, then it is a composite number.
The factors of 4070 are as follows:
1, 2, 5, 10, 11, 22, 37, 55, 74, 110, 185, 370, 407, 814, 2035, 4070
Therefore, since 4070 is divisible by more than one and itself, the answer to the
question "Is 4070 prime or composite?" is highlighted in blue below.
composite
Is 4071 prime or composite?
