Negative numbers aren't considered factors

Prime numbers can only be divided by 1 and themselves, excluding 1.
For example:
7 is prime because its factor are 1 and 7.
6 is not a prime because its factors are 1, 2, 3, and 6.

prime numbers are numbers whose only divisor is itself and one. so yes 1 and 3 are factors of 3, but 3 is still a prime number.

3 has 1 and 3 as its factors, right. so its a prime factor. bt we dont count negative nos as factors.. atleast i'm not able to recall ne negative number taken as factors, n i also believe that same is the case with multiples n divisors also.

Hmmmm. '1' is a factor for everything, even '0' so it doesn't count!!!
Any number that has no other factors than itself (and '1', since '1' doesn't count) is a prime number, divisible only by itself to obtain '1'!!!
Glad you're thinking, though!
