LCM for 20 and 335
What's the Least Common Multiple (LCM) of 20 and 335?
Answer
(One thousand, three hundred forty)
Finding LCM for 20 and 335 using GCF of these numbers
The first method to find LCM for numbers 20 and 335 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 20 and 335 is 5, so
LCM = (20 × 335) ÷ 5
LCM = 6700 ÷ 5
LCM = 1340
