$42$ / $42$
Correct Answer: $42$ / $42$
$84 = 2^2 \times 3 \times 7$, $126 = 2 \times 3^2 \times 7$, $210 = 2 \times 3 \times 5 \times 7$. The common prime factors give $2 \times 3 \times 7 = 42$. / $84 = 2^2 \times 3 \times 7$, $126 = 2 \times 3^2 \times 7$, $210 = 2 \times 3 \times 5 \times 7$। उभयनिष्ठ अभाज्य गुणनखंडों से $2 \times 3 \times 7 = 42$।
