To determine if 2860 is a prime number or a composite number, we simply look at the factors for 2860.
If the factors of 2860 are only 2860 and 1, then we know that 2860 is a prime number. Otherwise, 2860 is a composite number.
To explain better, if 2860 is only divisible by 1 and 2860, then it is a prime number, and if 2860 is divisible by more than 2860 and 1, then it is a composite number.
The factors of 2860 are as follows:
1, 2, 4, 5, 10, 11, 13, 20, 22, 26, 44, 52, 55, 65, 110, 130, 143, 220, 260, 286, 572, 715, 1430, 2860
Therefore, since 2860 is divisible by more than one and itself, the answer to the
question "Is 2860 prime or composite?" is highlighted in blue below.
composite
Is 2861 prime or composite?
