Question

HCF of a number is 6 and their LCM is 36. if one of them is 18, find the other number​

Answer 1

Answer: Product of two numbers=HCF×LCM

If one number=12

Let other be x & HCF=6, LCM=36

by subtituting we get,

12x=36×6

x=  

12

36×6

​

 

x=18.

Step-by-step explanation:

Answer 2

The HCF of two numbers is 6

The LCM of two numbers is 36

Let the numbers be a and b

According to question

(a×b) = HCF×LCM  

HERE a = 18 , Hcf = 6 , LCM = 36  

WE have to find b  

18×b = 6×36

b= 6× 36/18  

b = 12

Therefore answer: - The other number is 12
