To determine if 2580 is a prime number or a composite number, we simply look at the factors for 2580.
If the factors of 2580 are only 2580 and 1, then we know that 2580 is a prime number. Otherwise, 2580 is a composite number.
To explain better, if 2580 is only divisible by 1 and 2580, then it is a prime number, and if 2580 is divisible by more than 2580 and 1, then it is a composite number.
The factors of 2580 are as follows:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 43, 60, 86, 129, 172, 215, 258, 430, 516, 645, 860, 1290, 2580
Therefore, since 2580 is divisible by more than one and itself, the answer to the
question "Is 2580 prime or composite?" is highlighted in blue below.
composite
Is 2581 prime or composite?
