Answer:
The answer is D
Step-by-step explanation:
To answer this question, you can list the factors of each number, starting with sixty-three. The factors of sixty-three are one, three, seven, nine, twenty-one, and sixty-three. The factors of one hundred fourteen are one, two, three, six, nineteen, thirty-eight, fifty-seven, and one hundred fourteen. The numbers sixty-three and one hundred fourteen have three as a common factor, so they are not relatively prime. The number three is also a factor of both sixty-three and ninety-nine. So, sixty-three and ninety-nine are not relatively prime. The factors of eighty-seven are one, three, twenty-nine, and eighty-seven. Here, three is a common factor of eighty-seven and sixty-three, so these two numbers are not relatively prime. The factors of twenty-five are one, five, and twenty-five. None of these factors, other than one, are a factor of sixty-three. This means that the only factor that twenty-five and sixty-three have in common is one. So, twenty-five and sixty-three are relatively prime.
