To determine if 6530 is a prime number or a composite number, we simply look at the factors for 6530.
If the factors of 6530 are only 6530 and 1, then we know that 6530 is a prime number. Otherwise, 6530 is a composite number.
To explain better, if 6530 is only divisible by 1 and 6530, then it is a prime number, and if 6530 is divisible by more than 6530 and 1, then it is a composite number.
The factors of 6530 are as follows:
1, 2, 5, 10, 653, 1306, 3265, 6530
Therefore, since 6530 is divisible by more than one and itself, the answer to the
question "Is 6530 prime or composite?" is highlighted in blue below.
