Question

If HCF (12, 40) = 40 + 4X, then X = ....​

Answer 1

Answer:

12 - 1,2,3,4,6,12

40 - 1,2,4,5,8,10,20,40

so, HCF of (12,40) is 4

=> 4 = 40+4X

=> 1 = 10+X

=> X = -9

Answer 2

Answer:

$\huge{\boxed{\rm{\pink{X=-9}}}}$

Step-by-step explanation:

Given that:-

Given numbers are 12 and 40

12=2×2×3

40=2×2×2×5

HCF of 12 and 40 =2×2=4

HCF (12,40)=4

according to the given problem,

HCF (12, 40) = 40 + 4X

=>4=40+4X

=>4=4(10+X)

=>4/4=10+X

=>1=10+X

=>10+X=1

=>X=1-10

=>X=-9

The value of X=-9
