The product of the HCF and LCM of the numbers 8 and 20 is

A160
B40
C4
D400
Answer & Solution
Correct answer: A. 160
1. HCF × LCM always equals the product of the two numbers. 2. $8 \times 20 = 160$. 3. (Check: HCF = 4, LCM = 40, and 4 × 40 = 160.) _Source: Karnataka SSLC (KSEEB) Class 10 Mathematics, Ch8 'Real Numbers', §8.3_
