Question

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

Answer 1

Answer:

hey mate

HCF = 2 , LCM = 36

numbers are 18 and a

LCM ×HCF = the product of number

36 × 2 = 18×a

72 = 18×a

72÷18 =a

4=a

hope it will help you

Answer 2

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
