The HCF of two numbers is 5 and their LCM is 750. If one of the numbers is 125, find the other number.

Correct option is D

Given:

HCF = 5

LCM = 750

One of the numbers = 125

We are to find the other number

Concept Used:
For any two numbers:

HCF × LCM = Product of the two numbers

Solution:

Other Number = $$\frac{5 \times 750}{125} = \frac{3750}{125} = 30$$​​
