To determine if 7070 is a prime number or a composite number, we simply look at the factors for 7070.
If the factors of 7070 are only 7070 and 1, then we know that 7070 is a prime number. Otherwise, 7070 is a composite number.
To explain better, if 7070 is only divisible by 1 and 7070, then it is a prime number, and if 7070 is divisible by more than 7070 and 1, then it is a composite number.
The factors of 7070 are as follows:
1, 2, 5, 7, 10, 14, 35, 70, 101, 202, 505, 707, 1010, 1414, 3535, 7070
Therefore, since 7070 is divisible by more than one and itself, the answer to the
question "Is 7070 prime or composite?" is highlighted in blue below.
composite
Is 7071 prime or composite?
