Answer:
(i) and (iii)
Step-by-step explanation:
Two integers are said to be co-prime if they do not share a common divisor different than 1.
(i). 343 and 1000 are co-prime (no common divisor except 1) ;
(ii). 616 and 1288 are not co-prime (common divisor 2, ... GCD is 56)
(iii). 169 and 950 are co-prime (no common divisor except 1)
(iv). 1386 and 3168 are not co-prime, common divisor 2, ... GCD = 198
