To determine if 4480 is a prime number or a composite number, we simply look at the factors for 4480.
If the factors of 4480 are only 4480 and 1, then we know that 4480 is a prime number. Otherwise, 4480 is a composite number.
To explain better, if 4480 is only divisible by 1 and 4480, then it is a prime number, and if 4480 is divisible by more than 4480 and 1, then it is a composite number.
The factors of 4480 are as follows:
1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 32, 35, 40, 56, 64, 70, 80, 112, 128, 140, 160, 224, 280, 320, 448, 560, 640, 896, 1120, 2240, 4480
Therefore, since 4480 is divisible by more than one and itself, the answer to the
question "Is 4480 prime or composite?" is highlighted in blue below.
