WebUse the LCM by GCF formula to calculate (6×10)/2 = 60/2 = 30; So LCM(6,10) = 30; A factor is a number that results when you can evenly divide one number by another. In this sense, a factor is also known as a divisor. The greatest common factor of two or more numbers is the largest number shared by all the factors.

WebOct 24, 2010 · GCD should a class with a bunch of overloaded static methods that takes in two numbers and gives it's gcd. And it should be part of the java.math package. – anu May 12, 2014 at 19:18 Add a comment 16 Answers Sorted by: 155 As far as I know, there isn't any built-in method for primitives. But something as simple as this should do the trick:
