LCM for 80 and 216

What's the Least Common Multiple (LCM) of 80 and 216?

Answer: LCM of 80 and 216 is 2,160

(Two thousand, one hundred sixty)

Finding LCM for 80 and 216 using GCF's of these numbers

The first method to find LCM for numbers 80 and 216 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 80 and 216 is 8, so

LCM = (80 × 216) ÷ 8

LCM = 17280 ÷ 8

LCM = 2160
