Question 1/1 Expert Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 7

यदि दो संख्याओं का अभाज्य गुणनखंड रूप \(2^3\times5^2\) और \(2\times3^2\times5\) है, तो उनका लघुत्तम समापवर्त्य क्या होगा?

If two numbers have prime factorisations \(2^3\times5^2\) and \(2\times3^2\times5\), what is their LCM?

Explanation opens after your attempt
Correct Answer

A. \(2^3\times3^2\times5^2\)

Step 1

Concept

LCM includes every prime factor with its highest exponent.

Step 2

Why this answer is correct

Highest powers are \(2^3\), \(3^2\), and \(5^2\).

Step 3

Exam Tip

For LCM, do not miss a prime factor that appears in either number. चरण 1: लघुत्तम समापवर्त्य में सभी अभाज्य गुणनखंड अपनी सबसे बड़ी घात के साथ लिए जाते हैं। चरण 2: (2) की बड़ी घात (3), (3) की घात (2), और (5) की बड़ी घात (2) है। चरण 3: लघुत्तम समापवर्त्य में कोई अभाज्य गुणनखंड छूटना नहीं चाहिए।
