To determine if 2230 is a prime number or a composite number, we simply look at the factors for 2230.
If the factors of 2230 are only 2230 and 1, then we know that 2230 is a prime number. Otherwise, 2230 is a composite number.
To explain better, if 2230 is only divisible by 1 and 2230, then it is a prime number, and if 2230 is divisible by more than 2230 and 1, then it is a composite number.
The factors of 2230 are as follows:
1, 2, 5, 10, 223, 446, 1115, 2230
Therefore, since 2230 is divisible by more than one and itself, the answer to the
question "Is 2230 prime or composite?" is highlighted in blue below.
composite
