To determine if 7230 is a prime number or a composite number, we simply look at the factors for 7230.
If the factors of 7230 are only 7230 and 1, then we know that 7230 is a prime number. Otherwise, 7230 is a composite number.
To explain better, if 7230 is only divisible by 1 and 7230, then it is a prime number, and if 7230 is divisible by more than 7230 and 1, then it is a composite number.
The factors of 7230 are as follows:
1, 2, 3, 5, 6, 10, 15, 30, 241, 482, 723, 1205, 1446, 2410, 3615, 7230
Therefore, since 7230 is divisible by more than one and itself, the answer to the
question "Is 7230 prime or composite?" is highlighted in blue below.
composite
Is 7231 prime or composite?
