if lcm and hcf of three number are 90 and 7. two number are 15 and 30.find the third number


brunoconti: the question is not right. since 7 is not a factor of neither 15 nor 30. then the hcf cannot be 7!!!!!
shadowsabers03: Yes, I'm thinking about it. How 7 be LCM?!
shadowsabers03: Sorry, HCF.

hcf*lcm=product of no

let the third no be x

90*7=15*30*x

x=1.5.......................ans
