LCM for 210 and 231
What's the Least Common Multiple (LCM) of 210 and 231?
(Two thousand, three hundred ten)
Finding LCM for 210 and 231 using GCF's of these numbers
The first method to find LCM for numbers 210 and 231 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 210 and 231 is 21, so
LCM = (210 × 231) ÷ 21
LCM = 48510 ÷ 21
LCM = 2310
