Answer 1

Answer:

31

Step-by-step explanation:

Since the numbers are co-prime, they contain only 1 as the common factor.

Also, the given two products have the middle number in common.

So, middle number= H.C.F. of 77 and 143

77=11 X 7

143= 11 X 13

H.C.F.=11

First number

$\frac{77}{11}$

Second number

$\frac{143}{11}=13$

So the Final Answer is

7+11+13=31
