LCM for 60 and 210
What's the Least Common Multiple (LCM) of 60 and 210?
(Four hundred twenty)
Finding LCM for 60 and 210 using GCF's of these numbers
The first method to find LCM for numbers 60 and 210 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 60 and 210 is 30, so
LCM = (60 × 210) ÷ 30
LCM = 12600 ÷ 30
LCM = 420
