Finding LCM for 126 and 140 using GCF's of these numbers

The first method to find LCM for numbers 126 and 140 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 126 and 140 is 14, so

LCM = (126 × 140) ÷ 14

LCM = 17640 ÷ 14

LCM = 1260
