What's the Least Common Multiple (LCM) of 80 and 665?

Answer: LCM of 80 and 665 is 10,640

(Ten thousand, six hundred forty)

Finding LCM for 80 and 665 using GCF's of these numbers

The first method to find LCM for numbers 80 and 665 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 80 and 665 is 5, so

LCM = (80 × 665) ÷ 5

LCM = 53200 ÷ 5

LCM = 10640
