Question

5. If HCF of two numbers is 4 and their product is 160, then their LCM is
(a) 40
(b) 60
(c) 80
(d) 120​

Answer 1

Answer:

a) 40

Step-by-step explanation:

Given-

• HCF of two numbers is 4
• The product of the numbers is 160

We know that,

{HCF (x,y) × LCM (x,y) = Product of the two numbers (x,y) } [ The numbers are x,y]

Let x be the LCM.

So,

=> 4 × x = 160

=> x = 160/4

=> x = 40

Therefore, the LCM of the two numbers is 40
