The best way to factorize according to me is to start from the basic form
for example, the one that you have cited the basic form is 7x11^2
then write it in the form
(7^0+7^1)(11^0+11^1+11^2)
Take out a number from each of the groups and the result would be one of the factors.
example 7^2x11^1 is a factor.
Hope this helps.

see the easiest way to factorize is you have to keep in mind prime nos. in ur mind as much as possible atleast uptoC wrote:Hi guys,
I need some help with basic quant:
What is the easiest way to factorize?
How do I proceed to factorize 847?
Thanks.
40
now keep trying in mind which could divide the given no.
start from 2 if it is even
start from 3 if it is odd
start from 5 if last digit is 5 or 0 .
and continue
like here I start with 3(8+4+7=19 so No)
straight forward i will go for 7 yes
847 /7 = 121 =11x11
so 847 = 7x11x11......that is the appropriate approach..

Thanks, very helpful explanation!
Another challenge I have with factoring is problems like this:
x^3-3x^2+2x
or
n^2-14n+49
I can factor these given some intuitive thinking and try-fail-method, but it takes me to much time.
Does anyone have a good method for this kind of factoring?
Thank you!
