Team Careers360 · Accepted Answer

Correct Answer: $\frac{1}{55}$

Solution : Given: The numbers are $\frac{4}{55}$, $\frac{2}{11}$, and $\frac{8}{22}$
Highest Common Factor (HCF) of fraction = $\frac{ ext{HCF of numerator}}{ ext{LCM of denominator}}$ where LCM is the Least Common Multiple.
HCF of (4, 2, 8) = 2
LCM of (55, 11, 22) = $11 imes 2 imes 5 = 110$
Highest Common Factor (HCF) of fractions $\frac{4}{55}$, $\frac{2}{11}$, and $\frac{8}{22}=\frac{2}{110}=\frac{1}{55}$
Hence, the correct answer is $\frac{1}{55}$.
