Re: Factoring....
The first thing I always look for is whether it is divisible by 2. Since your number does not end in an even number it is not divisible by 2. The next step is to see if it is divisible by 3. If the sum of the digits is a multiple of 3, the number is divisible by 3. So, I would divide by 3 until the obtained quotient is not divisible by 3. Next, is the result divisible by 5? The final digit must be a 5 or a 0 to be divisible by 5. Next I would try 7, then 11, then 13, etc. until I have a prime number left. So, get busy, and I'm sure you can do it.
