To determine if 5720 is a prime number or a composite number, we simply look at the factors for 5720.
If the factors of 5720 are only 5720 and 1, then we know that 5720 is a prime number. Otherwise, 5720 is a composite number.
To explain better, if 5720 is only divisible by 1 and 5720, then it is a prime number, and if 5720 is divisible by more than 5720 and 1, then it is a composite number.
The factors of 5720 are as follows:
1, 2, 4, 5, 8, 10, 11, 13, 20, 22, 26, 40, 44, 52, 55, 65, 88, 104, 110, 130, 143, 220, 260, 286, 440, 520, 572, 715, 1144, 1430, 2860, 5720
Therefore, since 5720 is divisible by more than one and itself, the answer to the
question "Is 5720 prime or composite?" is highlighted in blue below.
composite
Is 5721 prime or composite?
