Hard Mathematics Chapter 1: Real Numbers Class 10 Level 12

यदि \(165=3\times5\times11\) और \(231=3\times7\times11\), तो इनके महत्तम समापवर्तक और लघुत्तम समापवर्त्य का योग क्या होगा?

If \(165=3\times5\times11\) and \(231=3\times7\times11\), what is the sum of their HCF and LCM?

Correct Answer

C. (1188)

Step 1

Concept

The common prime factors are (3) and (11), so HCF (=33).

Step 2

Why this answer is correct

LCM \(=3\times5\times7\times11=1155\), so the sum is (33+1155=1188).

Step 3

Exam Tip

When sum is asked, find both values separately. चरण 1: समान अभाज्य गुणनखंड (3) और (11) हैं, इसलिए महत्तम समापवर्तक (33) है। चरण 2: लघुत्तम समापवर्त्य \(3\times5\times7\times11=1155\) है, इसलिए योग (33+1155=1188) है। चरण 3: योग पूछे जाने पर दोनों मान अलग-अलग निकालें।
