The only common factor is: 1
Since there are no common prime factors of 7 and 27, you must multiply them together to get the common denominator. 27 times 7 is 189.
7 and 1
The factors of 27 are 1, 3, 9, and 27. The factors of 63 are 1, 3, 9, 7, 21, and 63. The common factors of 27 and 63 are 1, 3, and 9.
27 and 14 don't have common factors other than 1. Factors of 27 are 1, 3, 9 and 27. Factors of 14 are 1, 2, 7 and 14. So only common factor is 1.
The factors of 35 are 1, 5, 7, and 35. The factors of 27 are 1, 3, 9, and 27. The only factor they have in common is 1; therefore, 35 and 27 are relatively prime. Alternatively, you can look at the prime factors. The prime factors of 35 are 5 and 7. The prime factors of 27 are 3, 3, and 3. They have no prime factors in common, so they are relatively prime, which means their only common factor is 1.
