Find the HCF and LCM of \( \Large \frac{HCF\ of\ 2,\ 4,\ 6}{LCM\ of\ 3.\ 9.\ 13} \)

A) 14
B) 12
C) 16
D) 18

Correct Answer:


B) 12

Description for Correct answer:
\( \Large \frac{3, 9, 13}{3} = 1,\ 3,\ 13 \)

=\( \Large \frac{2}{117} \)

\( \Large \frac{LCM\ of\ 2,\ 4,\ 6}{HCF\ of\ 3,

9,\ 13} \)

=\( \Large \frac{2,\ 4,\ 6}{2} = 1,\ 2,\ 3 \)

=\( \Large \frac{12}{1} = 12 \)
