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.
