Which of the following is not a prime factorisation?

Explanation opens after your attempt
Correct Answer

C. \(4\times3\)

Step 1

Concept

In prime factorisation, all factors must be prime.

Step 2

Why this answer is correct

In \(4\times3\), 4 is not prime, so this is not prime factorisation.

Step 3

Exam Tip

If a composite factor appears, factorise it further. चरण 1: अभाज्य गुणनखंडन में सभी गुणनखंड अभाज्य होने चाहिए। चरण 2: \(4\times3\) में 4 अभाज्य नहीं है, इसलिए यह अभाज्य गुणनखंडन नहीं है। चरण 3: यदि कोई संयुक्त गुणनखंड दिखे तो उसे आगे तोड़ें।
