To determine if 7090 is a prime number or a composite number, we simply look at the factors for 7090.
If the factors of 7090 are only 7090 and 1, then we know that 7090 is a prime number. Otherwise, 7090 is a composite number.
To explain better, if 7090 is only divisible by 1 and 7090, then it is a prime number, and if 7090 is divisible by more than 7090 and 1, then it is a composite number.
The factors of 7090 are as follows:
1, 2, 5, 10, 709, 1418, 3545, 7090
Therefore, since 7090 is divisible by more than one and itself, the answer to the
