Answer:
119 and 209 is the only pair of relatively prime number.
Step-by-step explanation:
We are given the following information:
Relatively Prime:
- If there is no integer greater than one that divides the two number, then the numbers are said to be relatively prime.
- In other words it could be said that the greatest common divisor of the two numbers is 1.
- For example, 12 and 13 are relatively prime, but 12 and 14 are not.
a) 119 and 209 - No shared factors. hence, they are co-prime.
b) 88 and 121 - The greatest common divisor is 11 and hence they are not relatively prime.
c) 144 and 165 - The greatest common divisor is 3 and hence they are not relatively prime.
d) 42 and 385 - The greatest common divisor is 7 and hence they are not relatively prime.
