Find the LCM And HCF of 6 and 20 by the prime factorization method.
Given :
Given numbers are 6 and 20.
To do :
We have to find the LCM and HCF of the given numbers by the prime factorization method.
Solution :
Prime factorisation of 6 is,
$6 = 2 \times 3$
Prime factorisation of 20 is,
$20 = 2 \times 2 \times 5$
Therefore,
LCM of 6 and 20 $= 3 \times 2 \times 2 \times 5 = 60$
HCF of 6 and 20 $= 2$.
Therefore, the HCF of 6 and 20 is 2, and the LCM of 6 and 20 is 60.
