Question

If the LCM of a and 18 is 36 and the HCF of a and 18 Is 2, then what is the value of a?​

Answer 1

Step-by-step explanation:

Given that, LCM(a, 18) is 36 and HCF(a,18) is 2. One of the numbers is known to us as 18. a = 72/18 = 4.

Answer 2

If lcm of a and 18 is 36 and the hcf of a and 18 is 2,find the value of a

$\huge{\underline{\underline{\mathrm{\purple{AnswEr}}}}}$

If lcm of "a" and 18 is 36 and the hcf of a and 18 is 2, then value of "a" is 4

Solution:

We have been given that the lcm of "a" and 18 is 36 and the hcf of a and 18 is 2.

We need to find the value of a.

The relation between L.C.M and H.C.F

product of the two numbers =L C M × H C F

Therefore, the we can substitute the known values in the formula to get the values of "a"

a × 18 = 36 × 2

a = 72/18

a = 4

Hence the value of unknown number "a" is 4
