Question
The LCM of two numbers is 1800 while their HCF is 36.
If one of the numbers is 432, then the other number is:Solution
Given:
- LCM of two numbers = 1800
- HCF of two numbers = 36
- One number = 432
Since,
HCF of two numbers × LCM of two numbers = First number × Second number
Second number = (36 × 1800) / 432 = 64800 / 432 = 150
So, the other number is 150.
