Correct Answer

A. (78) और (286)(78) and (286)

Step 1

Concept

\(78=26\times3\) and \(286=26\times11\).

Step 2

Why this answer is correct

Since (3) and (11) are coprime, HCF is (26) and LCM is \(26\times3\times11=858\).

Step 3

Exam Tip

In options, factor out the HCF and check whether the remaining numbers are coprime. चरण 1: \(78=26\times3\) और \(286=26\times11\) हैं। चरण 2: (3) और (11) सहाभाज्य हैं, इसलिए महत्तम समापवर्तक (26) और लघुत्तम समापवर्त्य \(26\times3\times11=858\) है। चरण 3: विकल्पों में महत्तम समापवर्तक बाहर निकालकर बची संख्याओं की सहाभाज्यता देखें।
