Step-by-step explanation:
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.
