The factors of 27 are 1, 3, 9, and 27. The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. The common factors are 1, 3, 9, and 27.
Since 18 is a factor of 54, all of its factors are common.
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.
The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The common factors are 1, 2, 3, 6, 9 and 18.
The greatest common factor of 18 and 54 is 18One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.The common factors are 1, 2, 3, 6, 9, and 18. Therefore, the greatest common factor is 18.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 18 are 2, 3, and 3.The prime factors of 54 are 2, 3, 3, and 3.The prime factors in common are 2, 3, and 3, so the greatest common factor is 2 x 3 x 3 = 18.Common factors of 54 and 18 are: 1, 2, 3, 6, 9, and 18.Common factors of 54 and 18 are: 1, 2, 3, 6, 9, and 18.
