Frequently Asked Questions
What is the difference between GCF and LCM?
The GCF (greatest common factor) is the largest whole number that divides every value in the set, while the LCM (least common multiple) is the smallest whole number that every value divides into evenly. For 12 and 18 the GCF is 6 and the LCM is 36.
Does it work with 3 or 4 numbers?
Yes. Leave any extra input blank to compute for 2, 3 or all 4 numbers, and the tool reports the GCF and LCM for exactly the values you filled in.
Where are GCF and LCM used in real life?
They are the core of working with fractions: the GCF simplifies fractions to lowest terms and the LCM finds the common denominator when adding or subtracting fractions with different bottoms.
