Hard Mathematics Chapter 1: Real Numbers Class 10 Level 11

दो संख्याओं का महत्तम समापवर्तक (6) है और वे (6r), (6s) हैं। यदि (r=7) और (s=8), तो उनका लघुत्तम समापवर्त्य क्या होगा?

The HCF of two numbers is (6), and the numbers are (6r), (6s). If (r=7) and (s=8), what is their LCM?

Correct Answer

A. (336)

Step 1

Concept

When (r) and (s) are coprime, LCM is (6rs).

Step 2

Why this answer is correct

(7) and (8) are coprime, so LCM \(=6\times7\times8=336\).

Step 3

Exam Tip

Factor out the HCF and check the remaining numbers. चरण 1: जब (r) और (s) सहाभाज्य हों, तो लघुत्तम समापवर्त्य (6rs) होगा। चरण 2: (7) और (8) सहाभाज्य हैं, इसलिए लघुत्तम समापवर्त्य \(6\times7\times8=336\) है। चरण 3: महत्तम समापवर्तक को बाहर निकालकर बची संख्याओं को देखें।
