Question

Given HCF (81,54)=27. Find their LCM

Answer 1

LCM is the lowest common multiple of the two numbers.

==============================

multiple of 81 = 81 , 162, 243, 324,

multiple of 54 = 54, 108, 162, ...

so 162 is the common multiple

therefore

162 is the LCM

Answer 2

Hi there !

HCF x LCM = Product of 2 numbers

Product of 2 numbers = 81 x 54 = 4374

HCF = 27

27 x LCM = 4374

LCM = 4374 / 27
= 162

Hope this Helps You !!!
