LCM for 120 and 324
What's the Least Common Multiple (LCM) of 120 and 324?
(Three thousand, two hundred forty)
Finding LCM for 120 and 324 using GCF's of these numbers
The first method to find LCM for numbers 120 and 324 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 120 and 324 is 12, so
LCM = (120 × 324) ÷ 12
LCM = 38880 ÷ 12
LCM = 3240
