Question

The LCM of two numbers is 216 and their HCF is 36. If one of the numbers is 72, find the other number.
(With Process)

Answer 1

Answer:

108

Step-by-step explanation:

Other number = LCM×HCF÷1st number

= 216×36÷72

= 108

Answer 2

Required Answer

Here in this question we are provided that the LCM of two numbers is 216 and their HCF is 36 and the one of the numbers is 72. And we are asked to find out the other number.

Let's us assume that, the other number be x.

We know that we have the required formula, if we are given with the LCM value, HCF value and the one number value, that is,

➙ LCM × HCF = One number × Other number

By using the formula and substituting all the given values in it, we get :

➙ 216 × 36 = 72 × x

➙ 7776 = 72 × x

➙ 7776 = 72x

➙ x = 7776/72

➙ x = 108$\:$

Therefore, the other number is 108.
