Question

The HCF of two numbers is 18 and their LCM is 630. If one of the number is 36, then the other number is

Answer 1

Answer:

the next answer should be 54

Answer 2

The other number is 315.

Let the required number be 'x'.

If the LCM and HCF of two numbers are given, then we know that,

Number 1 × Number 2 = HCF × LCM

Given, number 1 = 36 and

Number 2 = x

LCM = 630 and,

HCF = 18.

So, by putting these values, we get:

36 × x = 630 × 18

⇒ x = (630 × 18)/36 = 315

This is the second number.
