The HCF and LCM of two natural numbers are 6 and 36,
respectively. What is the difference between the two numbers, if one of the numbers is 18?Solution
Given:
- HCF = 6
- LCM = 36
- First number = 18
Using the formula:
HCF × LCM = First number × Second number
6 × 36 = 18 × Second number
216 = 18 × Second number
Second number = 216 / 18 = 12
