Answer 1

Answer:

$\huge\orange{360}$

Step-by-step explanation:

Prime Factorisation:

$1440 = 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3 \times 5$

$1800 = 2 \times 2 \times 2 \times 3 \times 3 \times 5 \times 5$

_________________________________

$H.C.F. = 2 \times 2 \times 2 \times 3 \times 3 \times 5$

$H.C.F. = {2}^{3} \times {3}^{2} \times 5$

$\orange{.°. \: H.C.F. = 360}$
