The LCM of the two numbers is 1440 and their HCF is 32. If the first number is 288, then find the second number.

Correct option is D

Given:

LCM of numbers =1440

HCF of numbers =32

Concept Used:

Multiple of LCM and HCF of two numbers is equal to multiple of two numbers.

Solution:

LCM × HCF = 1st number × 2nd Number

2nd Number = $$\frac{1440×32}{288}= 160$$​​
