To determine if 8456 is a prime number or a composite number, we simply look at the factors for 8456.
If the factors of 8456 are only 8456 and 1, then we know that 8456 is a prime number. Otherwise, 8456 is a composite number.
To explain better, if 8456 is only divisible by 1 and 8456, then it is a prime number, and if 8456 is divisible by more than 8456 and 1, then it is a composite number.
The factors of 8456 are as follows:
1, 2, 4, 7, 8, 14, 28, 56, 151, 302, 604, 1057, 1208, 2114, 4228, 8456
Therefore, since 8456 is divisible by more than one and itself, the answer to the
question "Is 8456 prime or composite?" is highlighted in blue below.
