How to find the LCM Lowest Common Multiple

Learn how to use a factor tree in order to find the lowest common multiple.
I find the LCM of 12 and 15.

Thanks man I forgot how to do this an hour before the exam and you saved me. God bless you.

To be honest ill rather watch YouTube math than learning in school because i easily get it and tomorrow is exam Thank you so much bro may god bless you 😊

I wish all math teachers were like this.

Instant subscribe helped me so much with my math homework, the Venn diagram method was just confusing for me, thank you

[innocencyike]

The easiest way to do it. It’s clear now. Thanks a bunch.

Explained it better than my own teacher by 10000x ❤

The thing I don’t like about this method is that you have to know tricks and whatnot Vs just understanding the English within the question. For deeper understanding I think it’s better to perform multiple for each number starting from one until you hit 60 for each number. Because that is the lowest multiple that they both have in common. But maybe I’m wrong

Tysm for tutoring it..worth it soo much❤❤

Alternatively, divide the product of the numbers by the highest/greatest common factor/divisor.
12 x 15 = 180
180 / 3 = 60

Not necessarily easier, though.

Create a factor tree, circle the prime number. Make a half - cross square and write down the numbers that are the question, with the circle number inside the square. Make the numbers that are bigger at the right of the paper. Bring down numbers, if you have same number in a row, bring 1 down. Multiple it and you are done.

Thank you It is an hr before the exam literal

How do you do 51 and 18?
I can't do it😢

[matiaspereira]

It works multiplying the numbers by each other but ONLY if the numbers are relatively prime. Relatively prime numbers are numbers whose biggest common divisor is 1

So this is a 47 second video that explains it better than a qualified maths teacher that teaches you 4 hours a week?

[cottardremy]

Thank you bro golly they make this thing soooo complicated for what? I’m 10 seconds i understand everything. You know how much time I just wasted on other videos?

[codingwithMoebon]

i have got the right person that simplifies math

[planetary-rendez-vous]

Ok but it's badly explained. Why is 3 put below the other 3? What if you have 24 (2x2x2x3), how much space do you make?

[kelsykivihya]

the only think that disturbs me is the multiplicationbut now thats easy

[ZarahBryers]

What should I do if it’s three numbers and not two is it just the same ?
