Question

If LCM of a and 18 is 36 and HCF of a and 18 is 2 then value of a is.
​

Answer 1

Answer:

we know that product of lcm and hcf is equal to the product of two numbers .

Here , lcm=36 , hcf=2, one number=18 , other number=a .

lcm × hcf=product of two numbers

or,36×2=a×18

or,a=(36×2)÷18

or ,a=4

Answer 2

Answer:

a = 4

Step-by-step explanation:

If the numbers given are a,b then

a×b = to product of LCM and HCF of a,b

so,

if we take 18 as b then,

18 × a = 36 × 2

a = 36×2 / 18

a = 4
