Answer: LCM of 168 and 231 is 1,848

(One thousand, eight hundred forty-eight)

Finding LCM for 168 and 231 using GCF's of these numbers

The first method to find LCM for numbers 168 and 231 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 168 and 231 is 21, so

LCM = (168 × 231) ÷ 21

LCM = 38808 ÷ 21

LCM = 1848
