This question is based on finding HCF by continued division method. Now according to the condition of the problem, Last divisor = 49 and Last quotient = 2 ∴ dividend = 49 × 2 = 98 Now, divisor = 98 and quotient = 3 and remainder = 49 ∴ dividend = 98 × 3 + 49 = 343 Now, divisor = 343, quotient = 17 and remainder = 98 ∴ Dividend = 343 × 17 + 98 = 5829 Therefore, these numbers are 343 and 5829 .
