Best ResponseYou've already chosen the best response.0Divide 360 by 270 and get the remainder first...

Best ResponseYou've already chosen the best response.0Or second thing you can do is to take prime factors of 270 and 360..

Best ResponseYou've already chosen the best response.0they are both fairly obviously divisible by 10 it is also clear that they are both divisible by 9? 27 is, as is 36 so we know they are both divisible by 90

Best ResponseYou've already chosen the best response.0i have to break it down.

Best ResponseYou've already chosen the best response.0therefore the greatest common factor is at least 90 \[360\div 90=4,270/90=3\] so 90 is the answer

Best ResponseYou've already chosen the best response.1i did this one a while ago find prime factors and look for common values 270 = 2*3*3*3*5 360 = 2*2*2*3*3*5 GCF = 2*3*3*5 = 90

Best ResponseYou've already chosen the best response.0"(Give the answer in the numerical form in the top box and in exponential form by filling in the boxes for exponents.)"

Best ResponseYou've already chosen the best response.0No. do not divide it properly see do like this: dw:1340813241962:dw Get the remainder 90?? This is not the answer yet.. Now divide the divisor 270 by the remainder ie 90... If it is wholly divisible then 90 is the GCF...

Best ResponseYou've already chosen the best response.0really? sometimes you need to do that if it is not completely obvious, but in this case that is a total waste of time. they are both divisible by 90 from your eyeballs
