Three numbers which are co-prime to one another are such that the product of the first two is 551 and that of last two is 1073. The sum of the three numbers is:

175
281
385
489

Answer:- 1

Explanation:-

Solution:

\begin{aligned} HCF of 551 and 1073 is 29 . So second number is 29 . \\ First number = \frac{551}{29} = 19. \\ Third number = \frac{1073}{29} = 37. \\ So, \\ Required Sum = 19 + 29 + 37 = 85. \end{aligned}

$\eqalign{ & {\text{HCF of 551 and 1073 is 29}}{\text{. So second number is 29}}{\text{.}} \cr & {\text{First number }} = {\text{ }}\frac{{551}}{{29}}{\text{ }} = {\text{ }}19. \cr & {\text{Third number }} = {\text{ }}\frac{{1073}}{{29}} = {\text{ }}37. \cr & {\text{So}}, \cr & {\text{Required Sum }} = {\text{ }}19 + 29 + 37{\text{ }} = {\text{ }}85. \cr}$
