Answer: 1
Definition: 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 12 are 1, 2, 3, 4, 6, and 12.
The factors of 19 are 1 and 19.
The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.
The GCF is 1.

What is the greatest common factor of 228?
There is not a greatest common factor of a single number, such as 228, because there cannot be a greatest 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 228 are 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, and 228. The prime factors of 228 are 2, 2, 3, and 19. Examples: The greatest common factor of 24 and 228 is 12. The greatest common factor of 57 and 228 is 57. The greatest common factor of 98 and 228 is 2. The greatest common factor of 169 and 228 is 1.
What is the greatest common factor of 7 and 19?
The GCF of 7 and 19 is 1.
