​

Answer 1

$\Large\underline\mathbb\blue{ANSWER}$

____________________________________

The Prime Factorisation of 26 and 54 gives:

$\tt27 =\underline{ 3 \times 3 \times 3 } = {3}^{3}$

$\tt 54 = 2 \times \underline{3 \times 3 \times 3} = 2 \times {3}^{3}$

Note: For any two positive integers, HCF is the product of the smallest power of each common prime factor in the numbers.
