${\red{\bold{\huge{\mathfrak{Answer}}}}}$

Step by step explanation:

➡First find the HCF of 9,12

$12 = 9 \times 1 + 3 \\ 9 = 3 \times 3 + 0$

Therefore we get the HCF as 3,

➡Now,divide 15 by the first HCF,that is 3,

$15 = 3 \times 5 + 0$

We get the HCF as 3,

Therefore HCF of 9,12,15 is

${\red{\huge{\boxed{3}}}}$

Answer 2

12 = 9 × 1 + 3

9 = 3 × 3 + 0

15 = 3 × 5 + 0

HCF = 3

OR

12 = 3 × 2 × 2

9 = 3 × 3

15 = 3 × 5

HCF = 3
