D. 8⁵​

{correct notation of the question}

Given:

8², 8³, 8⁴, 8⁵

To find:

HCF of  8², 8³, 8⁴, 8⁵

Solution:

HCF is the highest common factor that means the common factors in the prime factorisation of the given set of numbers.

HCF is just the largest common number in the set of the different numbers or you can say the multiple of the HCF.

We have given the numbers as:

8², 8³, 8⁴, 8⁵

Here you can clearly see that  8² is common in all the numbers and that is the greatest in all.

So

The HCF of  8², 8³, 8⁴, 8⁵ is 8².
