Answer

LCM of 90 and 385 is 6,930

(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

GCF of numbers 90 and 385 is 5, so

LCM = (90 × 385) ÷ 5

LCM = 34650 ÷ 5

LCM = 6930
