किस अभाज्य गुणनखंडन से सम संख्या बनेगी?

Which prime factorisation will form an even number?

Explanation opens after your attempt
Correct Answer

C. \(2 \times 3 \times 7\)

Step 1

Concept

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

Step 2

Why this answer is correct

Only the third option contains (2), so it forms an even number.

Step 3

Exam Tip

You do not need to calculate the whole number to check even or odd. चरण 1: सम संख्या के अभाज्य गुणनखंडन में (2) अवश्य होता है। चरण 2: केवल तीसरे विकल्प में (2) है, इसलिए वही सम संख्या बनाएगा। चरण 3: सम या विषम पहचानने के लिए पूरी संख्या निकालने की जरूरत नहीं होती।
