LCM for 80 and 300
What's the Least Common Multiple (LCM) of 80 and 300?
(One thousand, two hundred)
Finding LCM for 80 and 300 using GCF's of these numbers
The first method to find LCM for numbers 80 and 300 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 80 and 300 is 20, so
LCM = (80 × 300) ÷ 20
LCM = 24000 ÷ 20
LCM = 1200
Finding LCM for 80 and 300 by Listing Multiples
