WebFactor trees (or prime factorization) can be an easy way to find the greatest common factor for two large numbers. Simply find all of the prime factors and identify the common factors. Multiply your common factors … WebHere’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.
