Well, honey, the greatest common factor of 12, 18, and 21 is 3. It's like finding the perfect little black dress that fits all three of them - simple, elegant, and always in style. So, grab your calculator and show those numbers who's boss!

The greatest common factor (GCF) of 12, 18, and 21 is the largest number that divides all three numbers without leaving a remainder. To find the GCF, you can first list the factors of each number: 12 (1, 2, 3, 4, 6, 12), 18 (1, 2, 3, 6, 9, 18), and 21 (1, 3, 7, 21). The GCF of 12, 18, and 21 is 3, as it is the largest number that is a factor of all three numbers.
