# LCM for 5 and 27

## What's the Least Common Multiple (LCM) of 5 and 27?

**Answer:**LCM of

**5 and 27**is

**135**

(One hundred thirty-five)

## Finding LCM for 5 and 27 using GCF's of these numbers

The first method to find LCM for numbers 5 and 27 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

**GCF of numbers 5 and 27** is **1**, so

LCM = (5 × 27) ÷ 1

LCM = 135 ÷ 1

LCM = 135

## Finding LCM for 5 and 27 by Listing Multiples
