Answer 2

$\huge{ \boxed{ \fcolorbox{cyan}{pink}{Answer}}}$

$\; \; \;$

Let's use Euclid's division lemma !

$\; \; \;$

$\bold \blue{ :\implies \: 161 = (13</strong><strong>1</strong><strong> </strong><strong> \times 1) + 30}$

$\bold \orange{ :\implies \: 131 = (30 \times 4) + 11}$

$\bold \blue{ :\implies \: 30 = (11\times 2) + 8}$

$\bold \orange{ :\implies \: 11 = (8\times 1) + 3}$

$\bold \blue{ :\implies \: 8 = (3\times 2) + 1}$

$\bold \orange{ :\implies \: 3 = (2\times 1) + 1}$

$\bold \pink{ :\implies \: 2 = (1\times 2) + 0}$

$\; \; \;$

$\boxed{ \fcolorbox{cyan}{black}{ \boxed{\bold \pink{ \boxed{ \fcolorbox{cyan}{orange}{ \boxed{\bold \purple{ Answer \implies \: HCF = 23 }}}}}}}}$
