कौन सा अभाज्य गुणनखंडन सम संख्या को दर्शाता है?

Which prime factorisation represents an even number?

Explanation opens after your attempt
Correct Answer

D. \(2 \times 3 \times 13\)

Step 1

Concept

An even number must contain (2) in its prime factorisation.

Step 2

Why this answer is correct

Only the fourth option contains (2), so it represents an even number.

Step 3

Exam Tip

You do not need to calculate the whole number to check evenness. चरण 1: सम संख्या के अभाज्य गुणनखंडन में (2) अवश्य होता है। चरण 2: केवल चौथे विकल्प में (2) है, इसलिए वही सम संख्या दर्शाता है। चरण 3: समता जांचने के लिए पूरी संख्या निकालने की जरूरत नहीं होती।
