LCM for 90 and 385
What's the Least Common Multiple (LCM) of 90 and 385?
Answer
(Six thousand, nine hundred thirty)
Finding LCM for 90 and 385 using GCF of these numbers
The first method to find LCM for numbers 90 and 385 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
