Tushborn: y | 8xy | 24y^2 2 | 8 | 24y 2 | 4 | 12y 2 | 2 | 6y 1 | 1 | 3y The explanation goes thus, we look for the common letter or figure that can go through the two given figure and the first "number/figure" we got was letter "y". After factoring "y", we were left with '24y' and '8'. When dealing with HCF, we must start with the smallest number that goes through the given figures and in this situation we have number '2'. You have to do this continuously until you get to a point where no number can go through the given figure. As can be seen above, the number '2' was factored three times after which we stopped. I hope you got it |

8(xy) = 1,2,4,and 8. (x,y) 24(y)^2= 1,2,3,4,8,12,and 24.(y.y) Therefore d h.c.f= 8. I don try here oya finish from there |

kelvinreality:Am not that cleared. how u came with that 8y as an answer? |
Re: Solve This Simple Mathematics by Tushborn: 11:21pm On May 01, 2017 |
Kylekent59:yea I understand this one. thanks |
Re: Solve This Simple Mathematics by Nobody: 11:25pm On May 01, 2017 |
Tushborn: Look below 8y = 2*2*2*y 24y^2 = 2*2*2*3*y*y when 24y^2 and 8y are being factored, what do you discovered? You clearly see that 2*2*2*y was common as of such the HCF Will be 8y. I hope you get it now 1 Like |

kelvinreality:which mistake? |
Re: Solve This Simple Mathematics by Nobody: 11:31pm On May 01, 2017 |
Tushborn:The guy that said the answer is '8' did mistake |
Re: Solve This Simple Mathematics by Tushborn: 11:31pm On May 01, 2017 |
kelvinreality:yea I got it. thumbs up |
Re: Solve This Simple Mathematics by Tushborn: 11:32pm On May 01, 2017 |
kelvinreality:yes I got it nw. thanks to y'all |
Re: Solve This Simple Mathematics by Kylekent59: 11:33pm On May 01, 2017 |
Tushborn:Yea he got it. 8y. But I have to say 8 only as my own. |
Re: Solve This Simple Mathematics by Nobody: 11:34pm On May 01, 2017 |
Tushborn:You are welcome. |
