Question

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

other number.​

Answer 1

Answer:

HCF=145

LCM= 2175

One number= 725

$second \: number = \frac{hcf \times lcm}{first \: number} \\ \\ = \frac{145 \times 2175}{725} \\ \\ \\ = 435$

Answer 2

Step-by-step explanation:

$LCM \: \times \: HCF = a \: \times \: b$

$2175 \: \times \: 145 = 725 \: \times \: b$

$315375 = 725 \: \times \: b$

$b = 315375/725$

$b = 435$
