Ever want to discover the LCM (identical because the LCD) for a couple of numbers, however, you don’t experience like spending hours writing out the multiples for the numbers and ready until you get a match.

Of path you want to do this — a lot! Example: each time you upload fractions with exclusive denominators you want to discover the not unusualplace denominator. That is the LCM.
Here’s a short manner to do this.
The handiest manner to train that is with the aid of using example, so that’s what I’ll do — with the aid of using locating the LCM for 18 and 30.
Step 1) Find the GCF for the 2 numbers.
For 18 and 30, GCF is 6.
Step 2) Divide that GCF into both number; it doesn’t depend which one you pick out, so pick out the only that’s less complicated to divide.
Choose 18. Divide 18 with the aid of using 6. Answer = three.
Step three) Take that solution and multiply it with the aid of using the alternative number.
three x 30 = 90
Step 4) Celebrate …
… due to the fact the solution you simply were given is the LCM. It’s that easy.
Note: in case you need to test that this approach does work, divide with the aid of using the alternative number, and spot in case you don’t get the identical solution.
