Question
The HCF and LCM of two natural numbers are 15 and 75,
respectively. What is the difference between the two numbers, if one of the numbers is 25?Solution
Given:
- HCF = 15
- LCM = 75
- First number = 25
Using the formula:
HCF × LCM = First number × Second number
15 × 75 = 25 × Second number
1125 = 25 × Second number
Second number = 1125 / 25 = 45
Difference between two numbers: 45 - 25 = 20
