To determine if 456 is a prime number or a composite number, we simply look at the factors for 456.
If the factors of 456 are only 456 and 1, then we know that 456 is a prime number. Otherwise, 456 is a composite number.
To explain better, if 456 is only divisible by 1 and 456, then it is a prime number, and if 456 is divisible by more than 456 and 1, then it is a composite number.
The factors of 456 are as follows:
1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
Therefore, since 456 is divisible by more than one and itself, the answer to the
question "Is 456 prime or composite?" is highlighted in blue below.
composite
Is 457 prime or composite?
OK. Now you know that 456 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
