Explanation opens after your attempt
Correct Answer

A. (11)

Step 1

Concept

\(91=7\times13\), \(143=11\times13\), and \(187=11\times17\).

Step 2

Why this answer is correct

There is no prime factor common to all three, so the HCF should be (1).

Step 3

Exam Tip

For three numbers, a common factor must be present in every number. चरण 1: \(91=7\times13\), \(143=11\times13\), \(187=11\times17\) है। चरण 2: तीनों में कोई समान अभाज्य गुणनखंड नहीं है, इसलिए महत्तम समापवर्तक (1) होना चाहिए। चरण 3: तीनों संख्याओं के लिए समान गुणनखंड सभी में होना जरूरी है।
