LCM for 168 and 231
What's the Least Common Multiple (LCM) of 168 and 231?
(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
