Given LCM a b the procedure for finding the LCM using GCF is to divide the product of the numbers a and b by their GCF i e a b GCF a b When trying to determine the LCM of more than two numbers for example LCM a b c find the LCM of a and b where the result will be q Then find the LCM of c and q The result will be the LCM of all GCF of 12 15 18 is 3 GCF 12 15 18 3 Ex 10 15 20 or 24 48 96 45 or 78902 89765 12345
The LCM calculator will determine the least common multiple of two to fifteen numbers for you no need to fret This calculation is essential when adding or subtracting fractions with different denominators check the adding fractions calculator if you want to do it with a dedicated tool This means that the GCF of 12 and 18 is 6 and the LCM of 12 and 18 is 36 Example 2 Three Numbers Now let s work a problem involving three numbers Find the GCF and LCM of 15 18 24 Find GCF and LCM of Three Numbers Example So The GCF of 15 18 and 24 is 3 And the LCM of 15 18 and 24 is 360

You can calculate GCF known as greatest common factor or greatest common divisor gcd and LCM known as least common multiple or lowest common denominator lcd The LCM and GCF calculator also called the LCD and GCD finder will determine the least common multiple and greatest common factor of a set of two to n numbers For instance given the numbers 15 and 18 their GCF is the biggest number that is a factor of that is that divides cleanly into each of 15 and 18 in this example the GCF is 3 How do you find the LCM There are two methods for finding the LCM of a pair of numbers
Least Common Multiple Examples LCM of 8 and 12 LCM of 6 and 8 LCM of 12 and 18 LCM of 9 and 12 LCM of 9 and 15 LCM of 3 and 9 LCM of 4 and 9 For any positive integer k gcf a k b k gcf a b k gcf a b lcm a b a b gcf a lcm b c lcm gcf a b gcf a c lcm a gcf b c gcf lcm a b lcm a c
