To determine if 5780 is a prime number or a composite number, we simply look at the factors for 5780.
If the factors of 5780 are only 5780 and 1, then we know that 5780 is a prime number. Otherwise, 5780 is a composite number.
To explain better, if 5780 is only divisible by 1 and 5780, then it is a prime number, and if 5780 is divisible by more than 5780 and 1, then it is a composite number.
The factors of 5780 are as follows:
1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 289, 340, 578, 1156, 1445, 2890, 5780
Therefore, since 5780 is divisible by more than one and itself, the answer to the
question "Is 5780 prime or composite?" is highlighted in blue below.
composite
Is 5781 prime or composite?
