Answer 2

Answer:

156

HCF = 13

One number = 117

Concept Used:

Number 1 = HCF× (a)

Number 2 = HCF× (b)

Let the ratio of two numbers be a : b

here 'a' and 'b' are co-prime numbers.

1st number = 117 and HCF = 13

⇒ 117 = 13 × a

⇒ a = 9

Step-by-step explanation:

Now option 3 = 156

⇒ 156 = 13 × b

⇒ b = 12

9 and 12 are not co-prime numbers.
