To determine if 4320 is a prime number or a composite number, we simply look at the factors for 4320.
If the factors of 4320 are only 4320 and 1, then we know that 4320 is a prime number. Otherwise, 4320 is a composite number.
To explain better, if 4320 is only divisible by 1 and 4320, then it is a prime number, and if 4320 is divisible by more than 4320 and 1, then it is a composite number.
The factors of 4320 are as follows:
1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 27, 30, 32, 36, 40, 45, 48, 54, 60, 72, 80, 90, 96, 108, 120, 135, 144, 160, 180, 216, 240, 270, 288, 360, 432, 480, 540, 720, 864, 1080, 1440, 2160, 4320
Therefore, since 4320 is divisible by more than one and itself, the answer to the
question "Is 4320 prime or composite?" is highlighted in blue below.
composite
