The greatest common factor gcf or gcd or hcf of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder for example for the set of numbers 18 30 and 42 the gcf 6 greatest common factor of 0. In mathematics the greatest common factor gcf also known as the greatest common divisor of two or more non zero integers a and b is the largest positive integer by which both integers can be divided it is commonly denoted as gcfa b for example gcf32 256 32 prime factorization method there are multiple ways to find the . The mathematics community should settle on one of the two the greatest common divisor of 6 and 12 equals 6 so it actually equals one of the numbers and that makes a lot of sense because 6 actually is divisible into 12. Earlier we found that the common factors of 12 and 30 are 1 2 3 and 6 and so the greatest common factor is 6 so the largest number we can divide both 12 and 30 exactly by is 6 like this 6 1230 25 6 the greatest common factor of 12 and 30 is 6 and so 1230 can be simplified to 25
