You can put this solution on YOUR website! (1) x*y =600
.
(2) (x*y)/ n = 60,,,,,subst in (1)
.
n*60 = 600,,,,,n=10
.
x=20,,,y=30,,,LCD (30),,,,,,60,, ,90,,,......
.
,,,,,,,,,,,,,,,,,,,(20),,40,,60,,80,,100,,......
.
Therefore LCD of 20,30 is 60
.
HCF = 20,,,2*2*5
.
,,,,,,30,,,2*3*5,,,,,,,HCF = 2*5 =10
