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.

What are the common factors and greatest common factor of 10 and 20?
1,2,5,10 are the common factors, and the Greatest Common Factor is 10.
What is the greatest common factor of 20 and 90?
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
What are the common factors and greatest common factor of 20?
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.

What is the greatest common factor of 20 and 55?
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.
What is the greatest factors of 20 ad 46?
Their greatest common factor is 2
What is the greatest common factor of 20 12 and 20?
The GCF of 12 and 20 is 4.The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 20 are 1, 2, 4, 5, 10, and 20.The factors they have in common are 1, 2, and 4. Therefore, 4 is the greatest common factor.The greatest common factor can also be determined from the prime factors by multiplying the common prime factors together.The prime factors of 12 are 2, 2, and 3.The prime factors of 20 are 2, 2, and 5.The common prime factors are 2 and 2, so the greatest common factor is 2 x 2 = 4.The greatest common factor of 12 and 20 is 4
What are the greatest common factors of 17 and 20?

What is the greatest common factor of 80 and 100?
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 both numbers have in common. 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 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. The common factors are 1, 2, 4, 5, 10, and 20. Therefore, the greatest common factor is 20.
