What is the easiest way to find the prime factors of such a large number? I took a very long time to solve this problem and it probably shouldn't have taken me this long...
Any tips or tricks would be much appreciated! Thank you in advance!
Hey,
There are no tricks to prime factorisation or at least I'm not aware of any. Irrespective, the given number is not hard to prime factorise.
To tell you the truth, when I started solving the question myself, my first thought on seeing the number was there is no way GMAT will ask me to factorise this. There has to be a better way.
After wasting a minute and failing to come up with an alternate method, I did what was needed. PRIME FACTORISATION! and to my surprise it was really easy. The only thing holding me back was my fear/thought.
I don't know why you took a really long time to solve this. If you were stuck on where to start factorising - JUST PICK A NUMBER. Start somewhere, move on, repeat!
Hope I helped you in some way.
