Question

HCF and LCM of two numbers is 9 and 459 respectively. If one of the numbers is 27, find the other number.

Answer 1

Answer:

153

Step-by-step explanation:

Let first number = a,

second number = b

a = 27 ( given )

HCF(a,b) = 9

and

LCM (a,b) = 459

To find:

Value of b

solution:

We know that,

product of two numbers = product of H.C.F and L.C.M

b = 9* 459/27

After cancellation, we get

b = 153

Therefore,

second number = b = 153

Answer 2

Step-by-step explanation:

given hcf=9

given lcm= 459

given one of the number=27

let the other number be x

there is a relation between all 4 given

hcf x lcm = product of two numbers

9 x 459 = 27x

x= 9 x 459/27

x = 153

using the above relation ,we can find the other number very easily
