Correct Answer - Option 1 : 1

Given:

We have to find the HCF of the largest one digit odd number and the smallest prime number

Concept Used:

Concept of HCF

HCF (Highest Common Factor): HCF of x and y is the highest common factor that can divide x and y exactly

For Example,

12 → Factors of 12 are 1, 2, 3, 4, 6 and 12

16 → Factors of 16 are 1, 2, 4, 8 and 16

Here common factors are 1, 2, and 4. But of these 4 is the largest/highest

HCF of 12 and 16 is 4

Calculation:

The largest one digit odd number is 9

Smallest prime number is 2

HCF of 9 and 2 is 1

∴ The HCF of the largest one digit odd number and the smallest prime number is 1.
