625 and 81 are relatively prime because they have common prime factors.

The factors of 35 are 1, 5, 7, and 35. The factors of 81 are 1, 3, 9, 27, and 81. The only factor they have in common is 1. Therefore, 1 is the greatest common factor. This means that 35 and 81 are relatively prime. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 35 are 5 and 7. 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 the only factor they have in common is 1.

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.

The GCF of 54 and 81 is 27One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.The factors of 81 are 1, 3, 9, 27, and 81.The common factors are 1, 3, 9, and 27. Therefore, the greatest common factor is 27.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 54 are 2, 3, 3, and 3.The prime factors of 81 are 3, 3, 3, and 3.The prime factors in common are 3, 3, and 3, so the greatest common factor is 3 x 3 x 3 = 27. Factors of 54: 1 2 3 6 9 18 27 54 Factors of 81: 1 3 9 27 81 The GCF of 54 and 81 is 27The Greatest Common Factor (GCF) is: 27 .27.

Answer:The greatest common factor of 49 and 81 is 1.The common factors of 49 and 81 are only 1.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 49 are 1, 7, and 49.The factors of 81 are 1, 3, 9, 27, and 81.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 49 are 7 and 7.The prime factors of 81 are 3, 3, 3, and 3.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.

The only prime factor of 81 is: 3.The prime factors of 225 are: 3 and 5.

The prime factors of 45 are 3, 3 and 5 The prime factors of 81 are 3, 3, 3 and 3. So two 3s are common to both numbers so 3 x 3 = 9 and that is the greatest common factor of the two.
