Question

The hcf two number is 6 and their LCM is 36. If one of the numbers is 18 . Find the other number

Answer 1

Let the other no. be x

HCF of 18 and x = 6

LCM of 18 and x = 36

So, HCF × LCM = Product of two numbers

6 × 36 = 18 × x

216 = 18x

x = 216 ÷ 18

x = 12

Hence the other number is 12.

Answer 2

Answer:

Second number is 12.

Step-by-step explanation:

Here,

HCF of a number is 6 and LCM is 36

.

Let other number is x.

Formula :- LCM×HCF = Product of two given number.

Therefore, 6*36 = 18*x

X = 6*36/18

X = 6*2

Therefore, X = 12.

Therefore, Other number is 12.
