Question

The LCM and HCF of two numbers are 504 and 18 respectively. Find the other number if one number is 126. Solve the sum

Answer 1

wkt,product of two numbers =lcm×hcf

therefore,,
126×x = 504×18
126×x =9072
x = 9072÷126
x = 72

therefore 72 is the other number

Answer 2

Answer:

The other number is 72.

Step-by-step explanation:

Given : The LCM and HCF of two numbers are 504 and 18 respectively.

To find : The other number if one number is 126 ?

Solution :

Let the other number be 'x'.

One number is 126.

HCF=18

LCM=504

We know,

$\text{Product of two numbers}=HCF\times LCM$

$126\times x=18\times504$

$x=\frac{18\times504}{126}$

$x=72$

Therefore, The other number is 72.
