To determine if 8920 is a prime number or a composite number, we simply look at the factors for 8920.
If the factors of 8920 are only 8920 and 1, then we know that 8920 is a prime number. Otherwise, 8920 is a composite number.
To explain better, if 8920 is only divisible by 1 and 8920, then it is a prime number, and if 8920 is divisible by more than 8920 and 1, then it is a composite number.
The factors of 8920 are as follows:
1, 2, 4, 5, 8, 10, 20, 40, 223, 446, 892, 1115, 1784, 2230, 4460, 8920
Therefore, since 8920 is divisible by more than one and itself, the answer to the
question "Is 8920 prime or composite?" is highlighted in blue below.
composite
Is 8921 prime or composite?
