Two of them.
To have common factors there must be at least two numbers.
Common factors have to go into both numbers. The only common factor of 20 and 27 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.

The common factors of 27 and 29 are only 1; the greatest common factor is 1.
The highest common factor of 54 and 27 is 27
The numbers are coprime. Their only common factor is 1.
Answer:The greatest common factor of 27 and 70 is 1.The common factors of 27 and 70 are only 1.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods: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 27 are 1, 3, 9, and 27.The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 27 are 3, 3, and 3.The prime factors of 70 are 2, 5, and 7.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.The GCF is 1.
27 and 57 have two common factors: 1, 3.
The common factors of 27 and 81 are 3, 9 and 27 One is usually included in factors of numbers unless otherwise specified.
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 27 are 1, 3, 9, and 27. The factors of 29 are 1 and 29. The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.
The numbers are coprime so the only common factor is 1.
There cannot be a least common factor of 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 least common factor would be the smallest common factor that all the numbers have, which would be 1.
