Question

the product of two numbers is 120 and their lcm is 40. what is their Hcf.​

Answer 1

Step-by-step explanation:

The product of two numbers = product of their HCF and their LCM.

So 120 = 40 x HCF

120/40 = HCF

HCF = 3

and thus the HCF of the two numbers = 3.

Answer 2

Answer-

=> 3

Explantation-

Given,

Product of two numbers = 120

Their LCM = 40

We know that,

=> LCM × HCF = a × b ( where a and b are some number)

Putting the values in the formula

$= > 40 \times hcf \: = 120 \\ = > hcf = \: \frac{120}{40} \\ = > hcf = 3$

Hope it helps :)
