To determine if 5130 is a prime number or a composite number, we simply look at the factors for 5130.
If the factors of 5130 are only 5130 and 1, then we know that 5130 is a prime number. Otherwise, 5130 is a composite number.
To explain better, if 5130 is only divisible by 1 and 5130, then it is a prime number, and if 5130 is divisible by more than 5130 and 1, then it is a composite number.
The factors of 5130 are as follows:
1, 2, 3, 5, 6, 9, 10, 15, 18, 19, 27, 30, 38, 45, 54, 57, 90, 95, 114, 135, 171, 190, 270, 285, 342, 513, 570, 855, 1026, 1710, 2565, 5130
Therefore, since 5130 is divisible by more than one and itself, the answer to the
question "Is 5130 prime or composite?" is highlighted in blue below.
composite
Is 5131 prime or composite?
