Hard Mathematics Chapter 1: Real Numbers Class 10 Level 12

यदि (140) और (196) का महत्तम समापवर्तक (28) है, तो उनका लघुत्तम समापवर्त्य क्या होगा?

If the HCF of (140) and (196) is (28), what will be their LCM?

Correct Answer

A. (980)

Step 1

Concept

Product of two numbers equals HCF times LCM.

Step 2

Why this answer is correct

LCM \(=\frac{140\times196}{28}=980\).

Step 3

Exam Tip

Divide (196) by (28) first to get (7), then multiply \(140\times7\). चरण 1: दो संख्याओं का गुणनफल महत्तम समापवर्तक और लघुत्तम समापवर्त्य के गुणनफल के बराबर होता है। चरण 2: लघुत्तम समापवर्त्य \(=\frac{140\times196}{28}=980\) है। चरण 3: पहले (196) को (28) से भाग देकर (7) लें, फिर \(140\times7\) करें।
