To determine if 5530 is a prime number or a composite number, we simply look at the factors for 5530.
If the factors of 5530 are only 5530 and 1, then we know that 5530 is a prime number. Otherwise, 5530 is a composite number.
To explain better, if 5530 is only divisible by 1 and 5530, then it is a prime number, and if 5530 is divisible by more than 5530 and 1, then it is a composite number.
The factors of 5530 are as follows:
1, 2, 5, 7, 10, 14, 35, 70, 79, 158, 395, 553, 790, 1106, 2765, 5530
Therefore, since 5530 is divisible by more than one and itself, the answer to the
question "Is 5530 prime or composite?" is highlighted in blue below.
composite
Is 5531 prime or composite?
