Question

what is the easiest way for me to find lcm of complicated numbers???

Answer 1

multiply all the numbers, it's the easiest, though works for 90% cases. u can't use shortcuts in this case... it's risky to do so

Hope it helps u

Answer 2

Wid example and wid Steps.....

Example:  whenever you add fractions with
different denominators you need to find the common denominator. That is the LCM.

Here’s a quick way to do this.

The only way to teach this is by example, so that’s what I’ll do — by finding the LCM for 18 and 30.

Step 1)  Find the GCF for the two numbers.

For 18 and 30, GCF is 6.

Step 2)  Divide that GCF into either number; it doesn’t matter which one you choose, so choose the one that’s easier to divide.

Choose 18. Divide 18 by 6. Answer = 3.

Step 3)  Take that answer and multiply it by the other number.

3 x 30  =  90

Step 4)  Celebrate …

… because the answer you just got is the LCM. It’s that easy.

Note:  if you want to check that this technique does work, divide by the other number, and see if you don’t get the same answer.
