I do it this way
15 x 23

10 x 23 = 230
5 x 23 = 115
230 + 115 = 345
or

23 x 15
20 x 15 = 300
3 x 15 = 45
300 + 45 = 345

I always try to get the prime factors first

So 15*23=3*5*23=3*115=345

Like take 224*1775

Break it down to
112*3550
then
56*7100
28*14200
14*24400
7*48800=341600

Now if this is wrong it will be embarassing...

Ah correction it goes from
28*14200
to
14*28400
then
7*56800=397600

oh wait, are you halving one side and doubling the other to the simplest form? does that really work?
User avatar #230 to #229 - jouten (02/24/2013) [-]
Yes, basically. You can do that because of the commutative property.

10 x 23 = 230
230 / 2 = 115
115 + 230 = 345
