Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Factors of 27: 1, 3, 9, 27
Factors of 15: 1, 3, 5, 15
GCF (30, 27, 15) = 3
1 and 3, are both the common factors and the GCF of 15 and 27.
The factors of 15 are: 1, 3, 5, 15.The factors of 27 are: 1, 3, 9, 27.The common factors are: 1, 3.The Greatest Common Factor (GCF) is: 3
The GCF of 15 and 27 is 3. One way to determine the 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 27 are 1, 3, 9, and 27. The common factors are 1 and 3. Therefore, 3 is the greatest common factor. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 15 are 3 and 5. The prime factors of 27 are 3, 3, and 3. The prime factors in common are a single 3, so the greatest common factor is 3.
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.
Factors of 15: 1, 3, 5, 15 Factors of 27: 1, 3, 9, 27 Factors of 35: 1, 5, 7, 35 GCF (15, 27, 35) = 1
The factors of 15 are: 1, 3, 5, 15The factors of 27 are: 1, 3, 9, 27The common factors are: 1, 3The Greatest Common Factor (GCF) is: 3
The greatest common factor of 27 and 33 is 3.
the greatest common factor of 27 and 48 is 3.
The greatest common factor of 27 and 35 is 1
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 27, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. Examples: The common factors of 27 and 29 are only 1; the greatest common factor is 1. The common factors of 27 and 33 are 1 and 3; the greatest common factor is 3. The common factors of 27 and 45 are 1, 3, and 9; the greatest common factor is 9. The common factors of 27 and 81 are 1, 3, 9, and 27; the greatest common factor is 27.
Common factors of 21 and 27 are: 1 and 3.
The greatest common factor of 30 and 135 is 15One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 135 are 1, 3, 5, 9, 15, 27, 45, and 135.The common factors are 1, 3, 5, and 15. Therefore, the greatest common factor is 15.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 30 are 2, 3, and 5.The prime factors of 135 are 3, 3, 3, and 5.The prime factors in common are 3 and 5, so the greatest common factor is 3 x 5 = 15.
