To determine if 5580 is a prime number or a composite number, we simply look at the factors for 5580.
If the factors of 5580 are only 5580 and 1, then we know that 5580 is a prime number. Otherwise, 5580 is a composite number.
To explain better, if 5580 is only divisible by 1 and 5580, then it is a prime number, and if 5580 is divisible by more than 5580 and 1, then it is a composite number.
The factors of 5580 are as follows:
1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 31, 36, 45, 60, 62, 90, 93, 124, 155, 180, 186, 279, 310, 372, 465, 558, 620, 930, 1116, 1395, 1860, 2790, 5580
Therefore, since 5580 is divisible by more than one and itself, the answer to the
question "Is 5580 prime or composite?" is highlighted in blue below.
composite
