Greatest Common Divisor: Euclid's Method, Recursive Procedure
29 Disember 2011
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.
In mathematics, the Euclidean algorithm (also called Euclid's algorithm) is an efficient method for computing the greatest common divisor (GCD) of two integers. It is named after the Greek mathematician Euclid, who described it in Books VII and X of his Elements.
Recursion in computer science is a method where the solution to a problem depends on solutions to smaller instances of the same problem. The approach can be applied to many types of problems, and is one of the central ideas of computer science.
"The power of recursion evidently lies in the possibility of defining an infinite set of objects by a finite statement. In the same manner, an infinite number of computations can be described by a finite recursive program, even if this program contains no explicit repetitions."
