No, they are not.
The Prime factors of 104 are 2 and 13.
Eleven numbers less than 105 are relatively prime to 105. They are 82, 83, 86, 88, 89, 92, 94, 97, 101, 103, and 104.
The prime factors of 112 are 2 and 7
No, they are not relatively prime.
No, they are not relatively prime.
No, they are not.
No
No. Even numbers can't be relatively prime to each other.
Yes. hcf(65, 112) = 1.
both are composite numbers
75 and 112
Yes, as their only common factor is 1.
The short answer is yes, 75 and 112 are relatively prime. The long answer is that any two numbers are considered to be relatively prime if they have no common factors other than 1. The prime factors of 75 are 3, 5, 5 since 3 x 5 x 5 = 75. The prime factors of 112 are 2, 2, 2, 2, 7 since 2 x 2 x 2 x 2 x 7 = 112. As you can see, there are no numbers in common in these lists of factors. Knowing this test, you can now determine for yourself if any set of numbers is relatively prime.
The greatest common factor of 112 and 104 is 8.
75,112
28 x 4 = 112
