Hard Mathematics Chapter 1: Real Numbers Class 10 Level 13

यदि दो संख्याएँ (30u) और (30v) हैं, जहाँ (u) और (v) सहाभाज्य हैं और (uv=26), तो उनका लघुत्तम समापवर्त्य क्या होगा?

If two numbers are (30u) and (30v), where (u) and (v) are coprime and (uv=26), what will be their LCM?

Correct Answer

C. (780)

Step 1

Concept

When (u) and (v) are coprime, the LCM of (30u) and (30v) is (30uv).

Step 2

Why this answer is correct

Since (uv=26), LCM \(=30\times26=780\).

Step 3

Exam Tip

Factoring out the HCF simplifies the question. चरण 1: जब (u) और (v) सहाभाज्य हों, तो (30u) और (30v) का लघुत्तम समापवर्त्य (30uv) होता है। चरण 2: (uv=26), इसलिए लघुत्तम समापवर्त्य \(30\times26=780\) है। चरण 3: महत्तम समापवर्तक को बाहर निकालने से प्रश्न सरल हो जाता है।
