Answer:

Explanation:

In HCF, will get a number which is common to both numbers 551 and 1073.

So hcf of 551 and 1073 is 29, which is one number among three numbers.

Let other two numbers be x and y

Given, x*29=551

x=551/29 = 19


Now,
y*29=1073
y = 2073/29 = 37

The three numbers. are 29,19,37

Sum = 29+19+37 = 85
