Now, Making factors of
Taking common:
Using <em>factorization</em> method:
The underlined parts show the Highest Common Factor(HCF).
i.e. <em>HCF</em> is .
We know the relation between <em>LCM, HCF</em> of the two numbers <em>'p' , 'q'</em> and the <em>numbers</em> themselves as:
Using equations <em>(1)</em> and <em>(2)</em>:
Hence, <em>LCM</em> =
