### Greatest Common Factor : Finding Made Easy - Lucid Explanation of an Efficient Method With Examples

Finding the largest positive integer that divides two or more numbers without remainder (G.C.F.) is an important topic in Elementary Number Theory. One way of finding the G.C.F. is by prime factorizations of the numbers. The second method based on the Euclidean algorithm, is more efficient and is discussed here. We provide lucid explanation of the method with a number of solved Examples.
