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

What is the greatest odd factor of \(2^5 \times 3\)?

Explanation opens after your attempt
Correct Answer

A. 3

Step 1

Concept

An odd factor must not contain (2).

Step 2

Why this answer is correct

Removing \(2^5\) leaves only (3), so the greatest odd factor is (3).

Step 3

Exam Tip

For the greatest odd factor, remove all powers of (2). चरण 1: विषम गुणनखंड में (2) नहीं होना चाहिए। चरण 2: \(2^5\) को हटाने पर केवल (3) बचता है, इसलिए सबसे बड़ा विषम गुणनखंड (3) है। चरण 3: सबसे बड़े विषम गुणनखंड के लिए सभी (2) हटा दें।
