Question

If the HCF of two numbers is 30 their LCM is 420 and one number is 210 then what is the other number

Answer 1

Answer:

Step-by-step explanation

HCF ×LCM= PRODUCT OF TWO NUMBERS

30×420= 210× second no.

Second no. = 30×420\210

Second no. = 30×2= 60

Answer 2

The value of other number is equal to 60.

Step-by-step explanation:

Given,

The HCF of two numbers = 30,

The LCM of two numbers = 420 and one number = 210

Let the other number = x

To find, the value of other number = ?

We know that,

LCM × HCF = Product of two numbers

∴ 210 × x = 30 × 420

⇒  $x =\dfrac{30 \times 420}{210}$

⇒ x = 30 × 2

⇒ x = 60

∴ The value of other number = 60

Thus, the value of other number is equal to 60.
