In mathematics, the greatest common divisor (gcd), also known as the greatest common factor (gcf), or highest common factor (hcf), of two or more non-zero integers, is the largest positive integer that divides the numbers without a remainder. For example, the GCD of 8 and 12 is 4.
This notion can be extended to polynomials, see greatest common divisor of two polynomials.

Famous quotes containing the words greatest and/or common:
“It’s a queer sensation, this secret belief that one stands on the brink of the world’s greatest catastrophe. For it means the fall of Western Europe, as it fell in the fourth century. It recurs to me every November, and culminates every December. I have to get over it as I can, and hide, for fear of being sent to an asylum.”
—Henry Brooks Adams (1838–1918)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
