Answer 1

Answer:

A. a,

Step-by-step explanation:

a. 5, 11

5 = 1,5

11 = 1,11

Only 1 is common factor

b. 6, 14

6 = 1,2,3,6

14 = 1,2,7,14

Here 1, 2 are common factors so 6 and 14 are not coprimes

c. 12, 15

12 = 1,2,3,4,6,12

15 = 1,3,5,15

Here 1,3 are common factors so 12 and 15 are not coprimes

d. 13, 52

13 = 1,13

52 = 1,2,4,13,26,52

Here 1, 13 are common factors so 13 and 52 are not coprimes
