If the LCM of a and 18 is 36 and the HCF of a and 18 is 2,


If the LCM of a and 18 is 36 and the HCF of a and 18 is 2, then a =

(a) 2

(b) 3

(c) 4

(d) 1


$\operatorname{LCM}(a, 18)=36$

$\operatorname{HCF}(a, 18)=2$

We know that the product of numbers is equal to the product of their HCF and LCM.


$18 a=2(36)$



Hence the correct choice is (c).
