The product of two numbers is 20000. If their LCM is 800, then what is their HCF?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 25.
The product of two numbers is 20000
Their LCM = 800
The product of two numbers = HCF × LCM
20000 = HCF × LCM
HCF × 800 = 20000
HCF = 20000/800 = 25
