Question

The hcf of two numbers is 27 and their lcm is 162 . If one of the number is 54 ,find the other?

Answer 1

Hello friend


One number is 54

So let the other number be y

We know that the product of two numbers will be equal to the product of their LCM and hcf.

54×y=27×162

y=27×162/54

y=162/2

y=81

The other number is 81

Hope it helps!

Answer 2

HI !

HCF = 27
LCM = 162

One no: = 54
Unknown no: = x

we know that ,
HCF x LCM = product of two no:s

27 x 162 = 54x
4374 = 54x

x = 4374/54
   = 81

∴ The other no: is 81
