LCM * HCF=product of 2 numbers(a*b)
168*HCF=504
HCF will be 3.
therefore 504 is product of 2 numbers which are multiples of 3..
find out those 2 numbers which are multiples of 3 and their product is 504.
504=2*2*2*3*3*7.=(8*3)*(3*7)
504=24*21...i.e., a=24 ,b =21
difference between products=(24*24)-(21*21)=576-441=135.
