To determine if 2456 is a prime number or a composite number, we simply look at the factors for 2456.
If the factors of 2456 are only 2456 and 1, then we know that 2456 is a prime number. Otherwise, 2456 is a composite number.
To explain better, if 2456 is only divisible by 1 and 2456, then it is a prime number, and if 2456 is divisible by more than 2456 and 1, then it is a composite number.
The factors of 2456 are as follows:
1, 2, 4, 8, 307, 614, 1228, 2456
Therefore, since 2456 is divisible by more than one and itself, the answer to the
question "Is 2456 prime or composite?" is highlighted in blue below.
