Find the common denominator of 3 more fractions

Learn to find the lowest common denominator (LCD) of three or more fractions
Use prime factorization in order to find these common denominators.
The lowest common denominator ( LCD ) is the smallest number that the denominators will divide into evenly.
For example, the LCD of 2,4, 8 is 8 because all three numbers will divide evenly into this number.

[mikesjovie]

could you please post more vid for more multiple LCD like 5 to 6 more fractions to find LCD

Guys, this doesn't always work my grade went ⬇ after this

[Tywil]

why wasnt the 6 is it because its not a prime number ?

[shannond]

what if you dont have denominators like that? for example, I have to do 1/6 - 2/3 + 1/4... HOW?

This doesn't work for 8, 9, and 15 -- the method at the following link does work:

bruh moment, i have 1/8 1/4 and 1/3 ._.

THIS DOES NOT WORK, DO NOT CROSS OUT PAIRS. multiply all the prime factors with last row quotient of common division.

This method doesn't always work. Example: 8 12 16 LCD=48 but using this method it comes out as 96. You get one too many 2's. Also doesn't work with 4 7 5 3

This is wrong - do not use - it won't work for all problems - go to link below by Wayne Ferguson for the Ladder Method. Unfortunately this is the one video that Google uses in it's search results as the example. Misinformation.
