Question

The HCF of two numbers is 144 and their LCM is 1440. If one of the number is 720 , find the other number .​

Answer 1

Given:

• HCF of two numbers = 144
• LCM of two numbers = 1440
• One of the number = 720

To Find:

• The other Number

Solution:

• Let the other number be x

❍ As we Know that,

LCM × HCF = Product of two numbers

➞ 144 × 1440 = x × 720

➞ 207360 = x × 720

➞ 207360/720 = x

➞ x = 288

Hence,

• The other number is 288.

Answer 2

Answer:

Correct answer is 288.

Step-by-step explanation:

We have, one number = 720

Let other number be x.

Now, product of numbers = HCF × LCM

⇒ 720 × x = 144 × 1440

$x = \frac{144 \times 1440}{720} = \frac{207360}{720} = 288$
