Lowest Common Multiple (Higher & Foundation) | GCSE Maths Tutor

A video revising the techniques and strategies for finding the lowest common multiple of two numbers and in context.
This video is part of the Number module in GCSE maths, see my other videos below to continue with the series.
These are the calculators that I recommend:
Casio fx-83GTX Scientific Calculator, Black - amzn.to/2P2cyGG
Casio Fx-991ex Scientific Calculator Fx 991 Ex - New + 552 Function - Classwiz - amzn.to/2sw2Moz

On the question talking about packs of holders and candles it should be 5 packs of holders and 2 packs of candles

[@HazeLeyHaKaz]

I saw that too, I forced my answer to be correct after seeing that error

[@platopyro]

ahhh yes. i too thrive off the failure of fellow humans

[@LegendFootballSkills]

@@platopyro wow i thrive in your speech as well

[@ayeshak7500]

The candle question there is an error, it should have been 2 candles , 5 candles holders

[@burpyjoe2310]

Yeah I agree

[@maz8652]

same thing he just mixed them but but yeah i guess

[@lindseymhirimo1918]

yeah

[@platopyro]

Thank you for pointing this out. I too saw this idiotic mistake. Being in set 8, I'm sure you can relate, I find it difficult to learn when my teacher makes such silly mistakes. Just the other day Mr Booth wrote on the board "Wednesday 12th of May". I of course corrected him on his pathetic error and proceeded to promise him that if he did it again I would punish him in ways so unfathomable to the natural human mind.

[@Napoloen08]

naa this is crazy @@platopyro

[@User-zl3yv]

haha 7:39 5 packs of what!? Oh gee, I like that you appreciated my idea of putting a few sneaky jokes every once in a while. oh gee, that was probably abt 4 years ago now

[@DeafPlayer19]

Shouldn’t candles should be packs 2 and the holders 5 packs? 10:01

[@aesthetic8147]

Yes he made a mistake

[@yaseenhussain]

For the last question, I don't understand why it is 11. I thought the answer was 10 because I did this: 360 secs = 6mins. 1hr = 60mins. 60/6=10 Answer is 10. Can you explain where I went wrong, please?

[@TheGCSEMathsTutor]

MYSTICXYZ17 Because of the one on zero second when it starts 😁🙏🏼

[@yaseenhussain]

@@TheGCSEMathsTutor oh ok I understand now, thanks

[@na092]

@@TheGCSEMathsTutor but wouldnt it be from 0 to 6 minutes, why is it just 0?

[@muzamilyasin8360]

@@na092 ‘alarms all start going off at the same time’ which means they went off at 0 then at 6

[@anaymakan6989]

@@na092 in the question it says the alarms all start going off at the same time so this would be the 10 + 1

OUTSTANDING TEACHING WITH CLEAR EXAMPLES

[@YaraYaraKada]

for the question talking about candles, isn't it 2 packs of candles and 5 packs of candle holders?

[@rubyreadal6607]

Thank you so much This was so helpful online school has been really hard but thx to u I got a 9 on my online mock

[@keyyframme6878]

Well done 👏 I wish had the same

[@Inspire_Success132]

3:24 The GCSE Maths Tutor You meant to circle 48 in multiples of 16, but circle 64 ,

[@hhh-nj9xc]

yall this is not gcse i learn this and im in year 9 so like the second year i have been in secondary school

[@maz8652]

it is GCSE.

[@hhh-nj9xc]

@@maz8652 not for me

[@lindseymhirimo1918]

they will be in ur GCSEs tho

[@tahminabegum4325]

you're so dumb mate everything you learn from year 5 to year 10 is literal gcse topics you won't know till you've done the test so shush

[@hassan.hadier]

learn everything properly so u can relax in y11 mate appreciate its in in ur GCSE this topic or r ya trynna make ur life harder for urself

[@rajabilawal1777]

That is so easy alhamdullilah l am passing math one day

[@jonerasmus9399]

Prime factorization method will also solve the pens and pencils ; 2x2x2x5 =40,. write prime factors common to both 8 and 20 only once in multiplication , then multiply the rest of the factors that are not in common .

[@IsabellaMatia]

This is so helpful Ty so much 🙏 I’ve learnt more from this video than I did from my maths teacher

[@muzamilyasin8360]

I had a question about the lowest common multiple for my exam but it said 98^73 98^62 98^87 98^53 98^86 and it said what’s the lowest common multiple. What category does this come under in maths?

[@tahminabegum4325]

SAME FR

[@Sol4rOnYt]

was it calculator? if it was shift+fact on a scientific calculator.

[@Sol4rOnYt]

you can use the prime factors to find LCM, but idk if it isn't

[@tahminabegum4325]

WHAT IF THE QUESTION IS p= 3^7 x 11^2 and Q = 7^3 x 11 WTF?

[@arthursimiao5023]

12:50 i thot was 10 but i forgot the 0 so is 11

[@rz6168]

same

[@GCSEALevelMaths]

Good video sir good. Keep up your hard work.

[@tahamuhammadismail329]

That is the best videos with compelling explanation I have ever seen. Thanks sir because of you maths is becoming more easier for me

[@Yaiena1111]

I used to think that it’s difficult until I found u

[@TheGCSEMathsTutor]

I’m so glad to hear that! 😁🙏🏼

[@ozguremek8509]

very nice way of finding LCM, only try to circle 48 instead of 64 at 03:30 ;)

[@YTGamerboyPG3D]

tysm helped me revise on these small topics!

[@dianachea715]

My grades are going down the graph 🥲.... I hope to Improve with you sir cuz my mathematics teacher is just a waste of energy.....😉

[@lidyahagos5586]

I can't understand the last one🤦‍♀️

thank you
