Question

1. The HCF and LCM of two numbers is 9 and 459 respectively. If one of the number is 27, then

the other number is​

Answer 1

We know,

HCF X LCM = Product of the number

Other number = 9 x 459 / 27 = 153 (Ans)

Answer 2

Answer:

153

Note:

• Product of two numbers us equal to product of their HCF and LCM , ie ;

a × b = HCF(a,b) × LCM(a,b)

Solution:

Let the required number be x.

Thus , we have ;

1st no. = 27

2nd no. = p

HCF = 9

LCM = 459

Now,

We know that ,

=> Product of two nos. = HCF × LCM

=> 27 × p = 9 × 459

=> p = 9 × 459 / 27

=> p = 153

Hence,

The required no. is 153 .
