Question

If ab = 60 and HCF (a,b) =4, then find the LCM (a,b)​

Answer 1

Step-by-step explanation:

we know,  

HCF(a,b)*LCM(a,b)=ab

            4*LCM(a,b)=60

   ∴          LCM(a,b)=60/4=15

hope this helps:)

Answer 2

Answer:

15 is the LCM (a,b)

Step-by-step explanation:

Explanation:

Given, that ab = 60 and

HCF of a and b = 4.

And we know that , product of LCM and HCF of any two numbers is equal to the product of the numbers.

Step 1:

From the property,

Product of the numbers = LCM × HCF

ab = LCM × HCF

⇒60 = LCM ×4

⇒LCM = $\frac{60}{4}$ = 15

Final answer:

Hence, the LCM of a and b is 15.
