Question

21. Find the HCF and LCM of a^2 b^3c^9 and b^2c^5d^3
where a, b, c, d are prime numbers.​

Answer 1

Step-by-step explanation:

Lcm =a^2 b^3c^9 d^3

Hcf=b^2 c^5

Answer 2

HCF$=b^2c^5$ and LCM$=a^2b^3c^9d^3$

Step-by-step explanation:

We have,

$a^2b^3c^9$ and $b^2c^5d^3$

To find, LCM and HCF of $a^2b^3c^9$ and $b^2c^5d^3=?$

The LCM of $a^2b^3c^9$ and $b^2c^5d^3$

The common factor of in any one

$=a^2b^3c^9d^3$

The HCF of $a^2b^3c^9$ and $b^2c^5d^3$

The common of both

$=b^2c^5$

∴ The LCM of $a^2b^3c^9$ and $b^2c^5d^3$$=a^2b^3c^9d^3$ and

The HCF of $a^2b^3c^9$ and $b^2c^5d^3$

$=b^2c^5$
