To determine if 6456 is a prime number or a composite number, we simply look at the factors for 6456.
If the factors of 6456 are only 6456 and 1, then we know that 6456 is a prime number. Otherwise, 6456 is a composite number.
To explain better, if 6456 is only divisible by 1 and 6456, then it is a prime number, and if 6456 is divisible by more than 6456 and 1, then it is a composite number.
The factors of 6456 are as follows:
1, 2, 3, 4, 6, 8, 12, 24, 269, 538, 807, 1076, 1614, 2152, 3228, 6456
Therefore, since 6456 is divisible by more than one and itself, the answer to the
question "Is 6456 prime or composite?" is highlighted in blue below.
