There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
There cannot be a greatest common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 55 are 1, 5, 11, and 55. The common factors are 1 and 5. Therefore, the greatest common factor is 5. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 20 are 2, 2, and 5. The prime factors of 55 are 5 and 11. The prime factors in common are a single 5, so the greatest common factor is 5.
The Greatest Common Factor of 20 and 90 is 10, because the factors of 20 are: 20:1,2,4,5,10,20 The factors of 90 are: 90:1,2,3,5,6,9,10,15,18,30,45,90 So, the common factors are 1,2,5,10 10 is the greatest number of them so 10 is the Greatest Common Factor. THE ANSWER IS 10
1,2,5,10 are the common factors, and the Greatest Common Factor is 10.
The factors of 17 are: 1, 17 The factors of 20 are: 1, 2, 4, 5, 10, 20 The common factors are: 1 The Greatest Common Factor: 1
There is neither a greatest common factor nor common factors of a single number, such as 20, 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. The factors of 20 are 1, 2, 4, 5, 10, and 20. The prime factors of 20 are 2, 2, and 5. Examples: The common factors of 20 and 70 are 1, 2, 5, and 10; the greatest common factor is 10. The common factors of 20 and 32 are 1, 2, and 4; the greatest common factor is 4. The common factors of 20 and 140 are 1, 2, 4, 5, 10, and 20; the greatest common factor is 20.
To find the greatest common factor of two numbers, you first need to split them into their prime factors. In this case, 20 and 27 can be broken down as follows: 20 = 2x2x5 27 = 3x3x3 The next step would be to identify any common factors. In this case there are none. Thus the greatest common factor of 20 and 27 is 1.
The Greatest Common Factor (GCF) of 20 and 36 is: 4
The Greatest Common Factor (GCF) is: 2
The greatest common factor is 10.
The greatest common factor of 14 and 20 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 14 are 1, 2, 7, and 14.The factors of 20 are 1, 2, 4, 5, 10, and 20.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 14 are 2 and 7.The prime factors of 20 are 2, 2, and 5.The prime factors in common are a single 2, so the greatest common factor is 2. Factors of 14: 1 2 7 14 Factors of 20: 1 2 4 5 10 20 The GCF of 14 and 20 is 2The GCF is 2.The GCF is 2.
