Question

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

Answer 1

Answer:

HCF×HCF=A×B

145×2175=725B

B=145×3= 435

Answer 2

Answer:

two numbers a and b is

Product of two numbers = HCF × LCM

____________________________

According to the given problem

HCF = 145 ,

LCM = 2175,

One number = a = 725

Let the second number = b

a × b = HCF × LCF

b = ( HCF × LCM ) / a

b = ( 145 × 2175 )/ 725

b = ( 145 × 3 × 725 )/ 725

After cancellation ,

b = 145 × 3

b = 435

Therefore ,

Second number = b = 435.
