To determine if 6545 is a prime number or a composite number, we simply look at the factors for 6545.
If the factors of 6545 are only 6545 and 1, then we know that 6545 is a prime number. Otherwise, 6545 is a composite number.
To explain better, if 6545 is only divisible by 1 and 6545, then it is a prime number, and if 6545 is divisible by more than 6545 and 1, then it is a composite number.
The factors of 6545 are as follows:
1, 5, 7, 11, 17, 35, 55, 77, 85, 119, 187, 385, 595, 935, 1309, 6545
Therefore, since 6545 is divisible by more than one and itself, the answer to the
question "Is 6545 prime or composite?" is highlighted in blue below.
