Answer: LCM of 120 and 324 is 3,240

(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
