LCM for 80 and 240
What's the Least Common Multiple (LCM) of 80 and 240?
(Two hundred forty)
Finding LCM for 80 and 240 using GCF's of these numbers
The first method to find LCM for numbers 80 and 240 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 80 and 240 is 80, so
LCM = (80 × 240) ÷ 80
LCM = 19200 ÷ 80
LCM = 240
