LCM for 160 and 180
What's the Least Common Multiple (LCM) of 160 and 180?
(One thousand, four hundred forty)
Finding LCM for 160 and 180 using GCF's of these numbers
The first method to find LCM for numbers 160 and 180 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 160 and 180 is 20, so
LCM = (160 × 180) ÷ 20
LCM = 28800 ÷ 20
LCM = 1440
