Answer 1

Since the numbers are co-prime, their HCF = 1
Product of first two numbers = 119
Product of last two numbers = 391
The middle number is common in both of these products.
Hence if we take HCF of 119 and 391, we get the common middle number.
HCF of 119 and 391 = 17
So, Middle Number = 17
First Number = 119/17 = 7
Last Number = 391/17 = 23
Sum of the three numbers = 7 + 17 + 23 = 47
