Answer: LCM of 66 and 210 is 2,310

(Two thousand, three hundred ten)

Finding LCM for 66 and 210 using GCF's of these numbers

The first method to find LCM for numbers 66 and 210 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 66 and 210 is 6, so

LCM = (66 × 210) ÷ 6

LCM = 13860 ÷ 6

LCM = 2310

Finding LCM for 66 and 210 by Listing Multiples
