Just 3
81 is not prime. Its prime factorization is 3x3x3x3.
The factors of 37 are 1 and 37. The factors of 81 are 1, 3, 9, 27, and 81. They have only one factor in common - 1. Since the greatest common factor of 37 and 81 is 1, they are relatively prime. You can also look at the prime factors to determine the greatest common factor. 37 is a prime number, so its only prime factor is itself, 37. The prime factors of 81 are 3, 3, 3, and 3. They have no prime factors in common, so they are relatively prime, which means their greatest common factor is 1.
3 x 3 x 3 x 3
18 and 81 share only one prime factor: 3
3 divides 81 without remainder (3*27 = 81) so 3 is a factor of 81. 3 cannot be divided without remainder by any number other than 1 and 3 itself, so 3 is a prime. Combining the two statements, 3 is a prime factor of 81.
