To determine if 2278 is a prime number or a composite number, we simply look at the factors for 2278.
If the factors of 2278 are only 2278 and 1, then we know that 2278 is a prime number. Otherwise, 2278 is a composite number.
To explain better, if 2278 is only divisible by 1 and 2278, then it is a prime number, and if 2278 is divisible by more than 2278 and 1, then it is a composite number.
The factors of 2278 are as follows:
1, 2, 17, 34, 67, 134, 1139, 2278
Therefore, since 2278 is divisible by more than one and itself, the answer to the
question "Is 2278 prime or composite?" is highlighted in blue below.
