To determine if 432 is a prime number or a composite number, we simply look at the factors for 432.
If the factors of 432 are only 432 and 1, then we know that 432 is a prime number. Otherwise, 432 is a composite number.
To explain better, if 432 is only divisible by 1 and 432, then it is a prime number, and if 432 is divisible by more than 432 and 1, then it is a composite number.
The factors of 432 are as follows:
1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
Therefore, since 432 is divisible by more than one and itself, the answer to the
question "Is 432 prime or composite?" is highlighted in blue below.
composite
Is 433 prime or composite?
OK. Now you know that 432 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.
