Question

the hcf of two numbers is 6 and their lcm is 36.if one number is 12 what is the other

Answer 1

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 = 12 , Hcf = 6 , LCM = 36  

WE have to find b  

12×b = 6×36

b= 6× 36/12  

b = 18.

Therefore answer: - The other number is 18

Answer 2

A.T.Q

12 * b = 36 * 6

B = 36 * 6 / 12

B = 18
