Question

What is the number x 9 . The lcm of x and 18 is 36 .the hcf of x and 18 is 2. a= 1 ,b = 3 ,c = 2 ,d = 4

Answer 1

Answer:

x is 4

Step-by-step explanation:

LCM of x and 18 is 36.

HCF is 2.

2 is not the factor of 1, 3. so we have 2 and 4 with us.

if x = 2 then the LCM would be 18. ( 2×9=18=18×1)

since LCM is 36, x = 4. (4×9 = 36 = 18×2)
