Question

Find the hcf of 120 and 144.

Answer 1

$120 = 2 \times 2 \times 2 \times 3 \times 5$
$144 = 2 \times 2 \times 2 \times 2 \times 3 \times 3$
so out of these 2 into 2 into 2 into 3 are common
therefore h.c.f of 120 and 140 =2×2×2×3
=24

Answer 2

Hay!!

Dear friend -

120 = 2 × 2 ×2 ×3 × 5
144 = 2 × 2 × 2 × 2 × 3 × 3

Then,

We found common 2×2×2×3

So,

H.C.F of 120 and 140

=> 2×2×2×3

=> 24

I hope it's help you
