To determine if 6465 is a prime number or a composite number, we simply look at the factors for 6465.
If the factors of 6465 are only 6465 and 1, then we know that 6465 is a prime number. Otherwise, 6465 is a composite number.
To explain better, if 6465 is only divisible by 1 and 6465, then it is a prime number, and if 6465 is divisible by more than 6465 and 1, then it is a composite number.
The factors of 6465 are as follows:
