Answer 2

Given ; 3*5^2 and 3^2*7^2

To Find ; LCM and HCF of two numbers

Solution ; 3*5^2 and 3^2*7^2 are given numbers

LCM is the lowest common factor

LCM  of  3*5^2 and 3^2*7^2=

3*5*5 and 3*3*7*7

3*5*5*3*7*7

=11025

So the LCM of  3*5^2 and 3^2*7^2 is 11025

HCF is highest common factor

HCF of  3*5^2 and 3^2*7^2

3*5^2 and 3^2*7^2

=3

Hence the LCM and HCF Is 11025 and 3 respectively
