Factors of 28 are 1, 2, 4, 7, 14, and 28.Factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54The common factors of 28 and 54 are 1 and 2
Answer: 1 The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. The common factors are 1 and 2; the least (or smallest) common factor is 1.
The GCF of 28 and 54 is 2. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. The common factors are 1 and 2. Therefore, the greatest common factor is 2. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 28 are 2, 2, and 7. The prime factors of 54 are 2, 3, 3, and 3. The prime factors in common are a single 2, so the greatest common factor is 2.
The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54 The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
2, 6, 18, 54
54 - 1, 2, 3, 6, 9, 18, 27, 54 56 - 1, 2, 4, 7, 8, 14, 28, 56 They each have 8 factors. They have a total of 16 factors together.
28/54 x 100 = 51.851 recurring (that is, 51.851851851...) percent.
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40 The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54 The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56
28 = 2 x 2 x 7, 54 = 2 x 3 x 3 x 3 so only common factor is 2
LCM of 28 and 54 is 756.
The factors of 54 are:1, 2, 3, 6, 9, 18, 27, 54The factors of 56 are:1, 2, 4, 7, 8, 14, 28, 56The common factors are:1, 2
