Answer 2

hey friend ✋✋

here's your answer ⏩⏩

$\bold{by \: prime \: factorisation \: method}$
$120 = 2 \times 2 \times 2 \times 3 \times 5 \\ 144 = 2 \times 2 \times 2 \times 3 \times 3 \\ \\ hcf = 2 \times 2 \times 2 \times 3 \\ \: \: \: \: \: \: \: \: = 24$
$\bold{by \: euclid \: division \: lemma}$
$120 < 144 \\ \\ 144 = 120 \times 1 + 24 \\ 120 = 24 \times 5 + 0 \\ \\ hcf = 24$



hope it helps u ✌✌
