Best Answer

There is neither a greatest common factor nor common factors of a single number, such as 19, 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 19 are 1 and 19.

The prime factor of 19 is 19.

Examples:

The common factors of 19 and 52 are only 1; the greatest common factor is 1.

The common factors of 19 and 95 are 1 and 19; the greatest common factor is 19.

The GCF of 19 and 57 is 19Definition: 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 19 are 1 and 19.The factors of 57 are 1, 3, 19, and 57.The common factors are 1 and 19. Therefore, the greatest common factor is 19.

One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 38 are 1, 2, 19, and 38. The factors of 95 are 1, 5, 19, and 95. The common factors are 1 and 19. Therefore, the greatest common factor is 19. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 38 are 2 and 19. The prime factors of 95 are 5 and 19. The prime factors in common are a single 19, so the greatest common factor is 19. 19. 2 times 19=38 5 times 19=95

The common factors are 1 and 19

The greatest common factor is 19

The only and therefore greatest common factor is 1.

The factors of 19 are: 1, 19 The factors of 76 are: 1, 2, 4, 19, 38, 76 The common factors are: 1, 19 The Greatest Common Factor: 19

The greatest common factor of 76 and 95 is 19.The factors of 76 are 1, 2, 4, 19, 38 and 76.The factors of 95 are 1, 5, 19 & 95.Therefore the greatest common factor is 19.

A factor is a number that divides into another number. Factors of 19 are 1 and 19. Factors of 49 are 1, 7, and 49. Therefore, 1 is the greatest common factor.

The only common factor is 1.

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 38, 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 38 and 40 are 1 and 2; the greatest common factor is 2. The common factors of 38 and 95 are 1 and 19; the greatest common factor is 19. The common factors of 38 and 101 are only 1; the greatest common factor is 1.
