यदि \(C_1={x:x\in \mathbb{N}, x\) (12) और (18) दोनों का गुणनखंड है(}) है, तो \(C_1\) क्या है?
If \(C_1={x:x\in \mathbb{N}, x\) is a factor of both (12) and (18)(}), what is \(C_1\)?
Explanation opens after your attempt
A. \(C_1={1,2,3,6}\)
Concept
(12) के गुणनखंड (1,2,3,4,6,12) हैं। / Factors of (12) are (1,2,3,4,6,12).
Why this answer is correct
(18) के गुणनखंड (1,2,3,6,9,18) हैं, इसलिए साझा गुणनखंड (1,2,3,6) हैं। / Factors of (18) are (1,2,3,6,9,18), so common factors are (1,2,3,6).
Exam Tip
संयुक्त गुणनखंड हमेशा सीमित संख्या में होते हैं। / Common factors are always finite in number.
