To determine if 5180 is a prime number or a composite number, we simply look at the factors for 5180.
If the factors of 5180 are only 5180 and 1, then we know that 5180 is a prime number. Otherwise, 5180 is a composite number.
To explain better, if 5180 is only divisible by 1 and 5180, then it is a prime number, and if 5180 is divisible by more than 5180 and 1, then it is a composite number.
The factors of 5180 are as follows:
1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 37, 70, 74, 140, 148, 185, 259, 370, 518, 740, 1036, 1295, 2590, 5180
Therefore, since 5180 is divisible by more than one and itself, the answer to the
question "Is 5180 prime or composite?" is highlighted in blue below.
composite
Is 5181 prime or composite?
