GCF=3The factors of 27 are: 1, 3, 9, 27The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90The factors of 135 are: 1, 3, 5, 9, 15, 27, 45, 135The common factors are: 1, 3, 9The Greatest Common Factor (GCF) is: 9
the first two common multiples of 15,27 are 135,270
The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The common factors are 1, 3, 5, and 15. Therefore, the greatest common factor is 15. You can also determine the greatest common factor from the prime factors. The prime factors of 45 are 3, 3, and 5. The prime factors of 60 are 2, 2, 3, and 5. The common prime factors are 3 and 5, so the greatest common factor is 3 x 5 = 15.
The factors of 15 are 1, 3, 5, and 15 The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60 The common factors of 15 and 60 are 1, 3, 5, and 15
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30Factors of 27: 1, 3, 9, 27Factors of 15: 1, 3, 5, 15GCF (30, 27, 15) = 3
The common factors of 108 and 150 are 1, 2, 3, and 6 with 6 being the greatest common factor.
Answer: 3Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method: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 15 are 1, 3, 5, and 15.The factors of 21 are 1, 3, 7, and 21.The factors of 27 are 1, 3, 9, and 27.The common factors are 1 and 3. Therefore, the greatest common factor is 3.
The common factors of 9, 18 and 27 are 1, 3, and 9.
The factors of 45 are: 1, 3, 5, 9, 15, 45The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54The common factors are: 1, 3, 9
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30 The factors of 81 are: 1, 3, 9, 27, 81 The common factors are: 1, 3
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.
Factors of 15: 1 3 5 15 Factors of 54: 1 2 3 6 9 18 27 54 Factors of 46: 1 2 23 46 The GCF of 15, 54, and 46 is 1
The factors of 30 are:1, 2, 3, 5, 6, 10, 15, 30The factors of 54 are:1, 2, 3, 6, 9, 18, 27, 54The common factors are:1, 2, 3, 6
Factors of 27: 1, 3, 9, 27Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30GCF (27, 30) = 3
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 common factors of 15 and 70 are 1 and 5
