To determine if 8280 is a prime number or a composite number, we simply look at the factors for 8280.
If the factors of 8280 are only 8280 and 1, then we know that 8280 is a prime number. Otherwise, 8280 is a composite number.
To explain better, if 8280 is only divisible by 1 and 8280, then it is a prime number, and if 8280 is divisible by more than 8280 and 1, then it is a composite number.
The factors of 8280 are as follows:
1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 23, 24, 30, 36, 40, 45, 46, 60, 69, 72, 90, 92, 115, 120, 138, 180, 184, 207, 230, 276, 345, 360, 414, 460, 552, 690, 828, 920, 1035, 1380, 1656, 2070, 2760, 4140, 8280
Therefore, since 8280 is divisible by more than one and itself, the answer to the
question "Is 8280 prime or composite?" is highlighted in blue below.
composite
Is 8281 prime or composite?
