Answer 2

Answer:

52 and 81

Step-by-step explanation:

By definition Co-prime numbers are the numbers whose common factor is only 1.

Factors of 52: 1, 2, 4, 13, 26, 52

Factors of 81: 1, 3, 9, 27, 81

Therefore, 52 and 81 are co-prime numbers.

Factors of 88: 1, 2, 4, 8, 11, 22, 44, 88

Factors of 187:  1, 11, 17, 187

Here, we can see that 11 is a common factor, therefore 88 and 187 are NOT co-prime numbers.
