Detailed Solution

The given numbers are 87 and 145.
We know that,
The formula which involves both HCF and LCM is:
(HCF of the two numbers)

\times

(LCM of the two numbers) = Product of Two numbers If ‘a’ and ‘b’ be two numbers, then we have,

a × b = H C F × L C M

Here, we have a = 87 and b = 145.

⇒ H C F × L C M = 87 × 145 = 12615

Hence,

(HCF × LCM)

of 87 and 145 is 12615.
So, option (4) is correct.
