The value of K is 15.

Step-by-step explanation:

Given : If (K-8) is the highest common factor of 56 and 77.

To find : What is the value of k ?

Solution :

The highest common factor of 56 and 77,

First we factor the numbers.

$56=2\times 2\times 2\times 7$

$77=7\times 11$

$HCF(56,77)=7$

We have given, (K-8) is the highest common factor of 56 and 77.
