Easy Mathematics Chapter 1: Real Numbers Class 10 Level 4

यदि \(40=2^3\times5\) और \(60=2^2\times3\times5\), तो दोनों का महत्तम समापवर्तक क्या है?

If \(40=2^3\times5\) and \(60=2^2\times3\times5\), what is their HCF?

Correct Answer

B. 20

Step 1

Concept

The common prime factors are 2 and 5.

Step 2

Why this answer is correct

The smaller powers are \(2^2\) and \(5^1\), so HCF is \(4\times5=20\).

Step 3

Exam Tip

For HCF, take smaller powers of common factors only. चरण 1: समान अभाज्य गुणनखंड 2 और 5 हैं। चरण 2: छोटी घातें \(2^2\) और \(5^1\) हैं, इसलिए महत्तम समापवर्तक \(4\times5=20\) है। चरण 3: महत्तम समापवर्तक में केवल समान गुणनखंडों की छोटी घात लें।
