Hard Mathematics Chapter 1: Real Numbers Class 10 Level 12

दो संख्याओं का गुणनफल (30240) है और उनका महत्तम समापवर्तक (42) है। उनका लघुत्तम समापवर्त्य क्या होगा?

The product of two numbers is (30240) and their HCF is (42). What will be their LCM?

Correct Answer

A. (720)

Step 1

Concept

Product of two numbers equals HCF times LCM.

Step 2

Why this answer is correct

LCM \(=\frac{30240}{42}=720\).

Step 3

Exam Tip

Simplifying the division first reduces mistakes. चरण 1: दो संख्याओं का गुणनफल महत्तम समापवर्तक और लघुत्तम समापवर्त्य के गुणनफल के बराबर होता है। चरण 2: लघुत्तम समापवर्त्य \(=\frac{30240}{42}=720\) होगा। चरण 3: भाग करते समय पहले (42) से सरल करना अच्छा तरीका है।
