I hope this may help u to clarify ur doubt

Answer 2

Answer:

Value of x=5

Step-by-step explanation:

Given : Numbers 77,99 and x.

To find : The HCF of the numbers?

Solution :

The prime factors are  

$77=7\times 11$    

$99=3\times 3\times 11$

$x=1\times x$

The HCF of 77,99 and x is  11.

The LCM of  77,99 and x is $LCM=7\times 11\times 3\times 3\times x$    

We have given, The LCM of 77,99 and x is  3465.

So, $3465=7\times 11\times 3\times 3\times x$    

$x=\frac{3465}{7\times 11\times 3\times 3}$    

$x=5$    

Therefore, The required value of x is 5.
