Question

The HCF of two numbers is 6 and LCM of the same numbers is 72. If one number is 18 find the other number.​

Answer 1

Answer:

Its too Easy

Step-by-step explanation:

LCM means lowest common factor so if one number is given you have to find the another one you have to subtract...

So: 72-18=54

Check: 54+18=72...

let's now check the hcf

Our numbers to check are 54 and 18 so

Divide 54 The HCF of 18 and 54 is 18. To calculate the Highest common factor of 18 and 54, we need to factor each number (factors of 18 = 1, 2, 3, 6, 9, 18; factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54) and choose the highest factor tha

Answer 2

Answer:

Given :

HCF of two numbers – 6

LCM of same numbers –72

One number – 18

What To Find?

Other number

Formula Using:

$\Huge \blue \mid \underline {\mathcal {{{\color{orange}{{ \: } \Large \begin{gathered} { {\boxed{ \sf {\red{HCF×LCM = First number× Second number}}}}}\end{gathered}}}}}} \blue\mid∣$

Solution:

6×72 = 18×Other number

Other number = $\frac{18}{432}$ = 24.

Hence, Other number = 24.
