Answer:

Hence, value of HCF of the given number will be 56

Step-by-step explanation:

In context to question asked,

We have to determine the value of HCF of given number.

As per question,

It is given that,

LCM of 560 and 840 is 8400

As here,

Value of numbers are - 560 and 840

Value of LCM is 8400

As we have,

Formula for finding the HCF if the value of LCM and numbers are given.

Number_1 \times Number_2 = LCM \times HCF

So, for finding the value of HCF we will put the value given in the question in above formula,

Thus we will get it as,

HCF = \frac{Number_1 \times Number_2}{LCM}\\=>HCF = \frac{560 \times 840}{8400}\\=>HCF = \frac{56\times 84}{84}\\=>HCF = 56
