The GCF is 1.
The factors of 17 are 1 and 17. The factors of 19 are 1 and 19. The only common factor is 1. Therefore, the least (lowest) common factor is 1 and the greatest (highest) common factor is 1.
19 is the greatest common factor. 19/19=1, 76/19=4.

The greatest common factor of 874 , 1995 = 19
The greatest common factor of 19 and 95 is 19.
The greatest common factor of 19 and 87 is 1.
The factors of 17 are 1 and 17. The factors of 19 are 1 and 19. The only common factor is 1. Therefore, the least (lowest) common factor is 1 and the greatest (highest) common factor is 1.
19 is the greatest common factor. 19/19=1, 76/19=4.
Greatest common factor for 19 and 24 is 1.
The greatest common factor of 19 and 38 is 19.
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.

1 One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 289 are 1, 17, and 289. The factors of 589 are 1, 19, 31, and 589. The common factors are 1. Therefore, the greatest common factor is 1; they 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 289 are 17 and 17. The prime factors of 589 are 19 and 31. There are no prime factors in common, which means they are relatively prime, so the greatest common factor is 1.
