Answer 2

Given : Two numbers are a and 18

Their LCM is 36 & HCF is 2


To find : Value of a


Solution :-

To find the value of a, we will use a formula. The formula is as follows :-

1st number × 2nd number = HCF × LCM

Let the 1st number be a and 2nd number be 18

Put the values in the above formula

☛ a × 18 = 2 × 36

☛ 18a = 72

☛ a = $\dfrac{72}{18}$

∴ a = 4


∴ The value of a is $\underline{\underline{\text{4}}}$
