LCM for 80 and 200
What's the Least Common Multiple (LCM) of 80 and 200?
(Four hundred)
Finding LCM for 80 and 200 using GCF's of these numbers
The first method to find LCM for numbers 80 and 200 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 80 and 200 is 40, so
LCM = (80 × 200) ÷ 40
LCM = 16000 ÷ 40
LCM = 400
Finding LCM for 80 and 200 by Listing Multiples
