$\huge{\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}$

Value of b= 9

Explaination -

☆ Given -

• HCF , LCM ( a,b) = 3, 36

☆ To find-

• Value of b

☆ Solution -

Using formula - HCF × LCM = Product of two no.

3 × 36 = a× b

108= 12 × b

108/12 = b

9 = b

Answer 2

Given:

H.C.F of two numbers a, b = 3

L.C.M of two numbers a, b = 36

The value of a = 12

To find :

The value of b

Calculation:

We know the relation :

   H.C.F × L.C.M = Product of two numbers

By substituting the given values in the above formula

⇒  H.C.F × L.C.M = a × b

⇒  3 × 36 = 12 × b

⇒  108 = 12 × b

⇒  b = 9

The value of b is 9
