Expert Mathematics Chapter 1: Real Numbers Class 10 Level 11

यदि (132) और (220) का महत्तम समापवर्तक (44) है, तो उनके लघुत्तम समापवर्त्य में (5) की घात क्या होगी?

If the HCF of (132) and (220) is (44), what will be the power of (5) in their LCM?

Correct Answer

B. (1)

Step 1

Concept

\(132=2^2\times3\times11\) and \(220=2^2\times5\times11\).

Step 2

Why this answer is correct

(5) appears only in the second number as \(5^1\), so its power in the LCM is (1).

Step 3

Exam Tip

A prime appearing in only one number is included in the LCM. चरण 1: \(132=2^2\times3\times11\) और \(220=2^2\times5\times11\) है। चरण 2: (5) केवल दूसरी संख्या में \(5^1\) के रूप में है, इसलिए लघुत्तम समापवर्त्य में इसकी घात (1) होगी। चरण 3: केवल एक संख्या में आया अभाज्य भी लघुत्तम समापवर्त्य में आता है।
