There are two numbers which are greater than 21 and their LCM and HCF are 3003 and 21 respectively. What is the sum of these numbers?
Answer & explanation
Correct answer: option 1
Product of other factors = \(\frac{LCM}{HCF}\) = \(\frac{3003}{21}\)
= 143
↓
Factors are: 1 × 143 or 11 × 13
Sum of these numbers = (11 + 13) × 21 = 504
