LCM for 30 and 385
What's the Least Common Multiple (LCM) of 30 and 385?
(Two thousand, three hundred ten)
Finding LCM for 30 and 385 using GCF's of these numbers
The first method to find LCM for numbers 30 and 385 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 30 and 385 is 5, so
LCM = (30 × 385) ÷ 5
LCM = 11550 ÷ 5
LCM = 2310
