Answer»

Answer:

Given: HCF (x,14) = 6,LCM (x,14) = 28

Mistake in the given question  

As we know that HCF is always a factor of LCM but in this question 6 is not the factor of  28.

Correct question:

If HCF ( x , 14 ) = 2 and LCM ( x , 14 ) = 28 then find the value of x

To Find : Value of x

Solution:

LCM of two numbers = 28  , HCF of two numbers = 6 and SECOND number = 14

We know that,

LCM x HCF = first number x second number

28 x 2  = x ×  14

First number = ( 28 x 2 ) /14  

First number = 56/14  

First number = 4  

HENCE, the value of x is 4.
