Hello can you please do a video about word problems of using LCM & GCD and how to figure out if we have to work out the word problem using a LCM or a GCD Thank you and i love your videos😀
There's a shorter way to find the GCF of 2 numbers: For every test number from 1 and continuing up, check to see if the smaller of the 2 numbers is divisible by it and if the other larger number is divisible by the quotient. If so, that's the GCF. Dividing a number by its smallest factor will always yield its largest factor as the quotient. Therefore if we start by dividing the smaller number by 1, 2, 3, etc... and checking to see if each resulting quotient is common to both, the first match we get will automatically be the GCF. You don't need to find all factors to determine GCF. And you can start by finding the largest factors first, so you know the first match must be the GCF. For example: Finding the GCF of 12 and 18: Is 12 divisible by 1? Yes, the quotient is 12. Now is 18 divisible by the quotient 12? No. So we move to our next test number :2. Is 12 divisible by 2? Yes, the quotient is 6. Now is 18 divisible by the quotient 6? Yes. Therefore 6 must be the GCF of 12 and 18. We can stop here.

You are helping me a lot Mr Johnson
Thank you for this Mr j I can do this now 🙏 thank you
you the goat Mr.J
Thank you!
멋진 수업이에요... 이해가 갑니다....정말 감사합니다, J 선생님! 🎉🎉
I'm going to have a test for an entrance exam in a high school this can really help thank you
Thank you Mr.J 🙏🩷🎉
Wow really helped me getting enrolled into a new school :)
thank you mr j.I appretiate this lesson
hi mr j remember me
What?
Yay
Thank you Mr j
Soo loonnngggg
Ai love this you make things so easy have a good day
thx
Please tell us how to do inequalities of the perimeter and more?
Cool❤
❤🎉
👋😁👋🚩
Kumon
My classmates do that too

bro this did not help i failed my college exam and had to work in mcdonalds everyday
Well still be thankful he did a lot of hardwork to make this video
@@DannahLexynVillanueva it was just a joke lol

Thx u for learning about Gcf and lcm but I want not remember this in my exam tho 🥲
