Hard Mathematics Chapter 1: Real Numbers Class 10 Level 13

यदि (154) और (231) का महत्तम समापवर्तक (77) है, तो उनका लघुत्तम समापवर्त्य क्या होगा?

If the HCF of (154) and (231) is (77), what will be their LCM?

Explanation opens after your attempt
Correct Answer

B. (462)

Step 1

Concept

For two numbers, LCM \(=\frac{\text{first number}\times\text{second number}}{\text{HCF}}\).

Step 2

Why this answer is correct

\(\frac{154\times231}{77}=462\).

Step 3

Exam Tip

First calculate \(154\div77=2\) for a quicker solution. चरण 1: दो संख्याओं के लिए लघुत्तम समापवर्त्य \(=\frac{\text{पहली संख्या}\times\text{दूसरी संख्या}}{\text{महत्तम समापवर्तक}}\) होता है। चरण 2: \(\frac{154\times231}{77}=462\) है। चरण 3: पहले \(154\div77=2\) करके गणना तेज करें।
