Question

The HCF of a number is 6 and their LCM is 36 if one of the number is 18 find the other number

Answer 1

Answer:

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

$b = 6 \times \frac{36}{18}$

$b = 6 \times \frac{6}{3}$

$b = 6 \times \frac{2}{1}$

b = 12
