What's the Least Common Multiple (LCM) of 80 and 645?

Answer: LCM of 80 and 645 is 10,320

(Ten thousand, three hundred twenty)

Finding LCM for 80 and 645 using GCF's of these numbers

The first method to find LCM for numbers 80 and 645 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 80 and 645 is 5, so

LCM = (80 × 645) ÷ 5

LCM = 51600 ÷ 5

LCM = 10320
