To determine if 7130 is a prime number or a composite number, we simply look at the factors for 7130.
If the factors of 7130 are only 7130 and 1, then we know that 7130 is a prime number. Otherwise, 7130 is a composite number.
To explain better, if 7130 is only divisible by 1 and 7130, then it is a prime number, and if 7130 is divisible by more than 7130 and 1, then it is a composite number.
The factors of 7130 are as follows:
1, 2, 5, 10, 23, 31, 46, 62, 115, 155, 230, 310, 713, 1426, 3565, 7130
Therefore, since 7130 is divisible by more than one and itself, the answer to the
question "Is 7130 prime or composite?" is highlighted in blue below.
composite
Is 7131 prime or composite?
