The HCF of two numbers is 20 and their LCM is 400. If one of the numbers is 80, then the other number is:
Given:
HCF of two numbers = 20
LCM of two numbers = 400
One of the numbers = 80
Formula Used:
Product of two numbers = HCF × LCM
Solution:
Let the two numbers be 'a' and 'b'.
a × b = HCF × LCM
80 × b = 20 × 400
80 × b = 8000
b = 100
