The HCF of two numbers is 145 and their LCM is 2175. If one of the numbers is 725, find the other.

Answer:

HCF of two numbers = 145

LCM of two numbers = 2175

Consider the one number as 725 and other be x.

Product of two numbers = HCF × LCM

725 × x = 145 × 2175

 

$$\matrix

{x = \frac{{145 \times 2175}}{{725}}} \hfill  \\

{\therefore x = 435} \hfill  \\

 

\endmatrix $$
