Calculate the HCF of 12 over 5,14 over 15 and 16 over 17 .

Calculate the HCF of ${{12} \over 5},{{14} \over 15}$ and ${{16} \over 17}$ .

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. ${{2} \over 255}$ .

Concept used:

To calculate the HCF of fractions = HCF of numerator/LCM of denominator

Calculations:

HCF of ${{12} \over 5},{{14} \over 15}$ and ${{16} \over 17}$ = (HCF of 12, 14 and 16)/(LCM of 5, 15 and 17)

⇒ 2/255
