Answer:

Hellow!

I guess the question is from secondary level,

HCF and LCM for the number 30,20 can be found in this way.

factors of 30 = 1 X 2 X 3 X 5

factors of 20 =1 X 2 X 2 X 5

HCF = 1 X 2 X 5

        = 10

HCF X LCM = a X b

LCM = ( a X b) / HCF

LCM = ( 20 X 30) / 10

LCM = 2X30       reduced into simplest form

LCM = 60
