LCM for 40 and 288
What's the Least Common Multiple (LCM) of 40 and 288?
(One thousand, four hundred forty)
Finding LCM for 40 and 288 using GCF's of these numbers
The first method to find LCM for numbers 40 and 288 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 40 and 288 is 8, so
LCM = (40 × 288) ÷ 8
LCM = 11520 ÷ 8
LCM = 1440
