If lcm of a and 18 is 36 and the HCF of a and 18 is 2, then the value of a is?
The LCM (least common multiple) and HCF(highest common factor) are connected with an empirical formula: LCM(a,b) × HCF(a,b) = Product of the numbers a and b
Answer: The value of a is 4.
Let's find the value of a.
Explanation:Given that, LCM (a, 18) is 36 and HCF (a,18) is 2. One of the numbers is known to us as 18.
So, by applying the formula: LCM × HCF = a × 18
36 × 2 = a × 18 72 = 18(a) 18a = 72 a = 72/18 = 4.
Hence, the value of a is 4.
If LCM of a and 18 is 36 and HCF of a and 18 is 2 then value a will be:

Correct option is D)
Since two numbers are and 18H.C.F =2 L.C.M =36
Product of both = H.C.F × L.C.M
a×18=2×36 a=4
Hence, correct choice is (d).
