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

यदि दो संख्याओं का अभाज्य गुणनखंड रूप \(2^3\times3^2\times5\) और \(2^2\times3^4\times7\) है, तो उनका महत्तम समापवर्तक क्या होगा?

If two numbers have prime factorisations \(2^3\times3^2\times5\) and \(2^2\times3^4\times7\), what is their HCF?

Correct Answer

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

Step 1

Concept

HCF contains only common prime factors.

Step 2

Why this answer is correct

The smaller power of (2) is (2), and the smaller power of (3) is (2). So HCF \(=2^2\times3^2\).

Step 3

Exam Tip

For HCF, choose the smaller exponent of common primes. चरण 1: महत्तम समापवर्तक में केवल समान अभाज्य गुणनखंड लिए जाते हैं। चरण 2: (2) की छोटी घात (2) और (3) की छोटी घात (2) है, इसलिए उत्तर \(2^2\times3^2\) है। चरण 3: महत्तम समापवर्तक के लिए छोटी घात चुनें।
