Hard Mathematics Chapter 1: Real Numbers Class 10 Level 6

यदि \(A=2^{10}\times3^6\times5^2\) और \(B=2^7\times3^8\times7^3\), तो (A) और (B) का महत्तम समापवर्तक कौन सा है?

If \(A=2^{10}\times3^6\times5^2\) and \(B=2^7\times3^8\times7^3\), which is the HCF of (A) and (B)?

Explanation opens after your attempt
Correct Answer

A. \(2^7\times3^6\)

Step 1

Concept

HCF uses only common prime factors.

Step 2

Why this answer is correct

The common factors are 2 and 3, with smaller powers \(2^7\) and \(3^6\).

Step 3

Exam Tip

Therefore, the HCF is \(2^7\times3^6\). चरण 1: महत्तम समापवर्तक में केवल समान अभाज्य गुणनखंड लिए जाते हैं। चरण 2: समान गुणनखंड 2 और 3 हैं, छोटी घातें \(2^7\) और \(3^6\) हैं। चरण 3: इसलिए महत्तम समापवर्तक \(2^7\times3^6\) है।
