The HCF of $\frac{3}{4}$ , $\frac{5}{7}$ , $\frac{7}{9}$ and $\frac{1}{12}$ will be:

Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. $\frac{1}{252}$ .

H.C.F of fraction = (H.C.F of numerator)/(L.C.M of denominator)

H.C.F of (3, 5, 7, and 1) = 1

L.C.M of (4, 7, 9, and 12) = 252

Hence,

H.C.F of fraction = 1/252
