HCF = 2

LCM = 144

Explanation:

16 = 2 x 2 x 2 x 2

18 = 2 x 3 x 3

Answer 2

First find hcf of 18 and 16.

And that is, 2.

how, now see here

16=2×2×2×2

18=2×3×3

As we saw in both there is two in vertical manner, so 2 is the HCF.

secondly find the lcm of 18 and 16.

And that is, 144.

how, now see here

with short division method, the answer is 2×2×2×3×3×2=144

And now multiple both the LCM and HCF( 18 AND 16) .

Now, 144×2=288.
