- In order to do a factor you need to draw 3 lines vertical and 3 horizontal.
- Then you write the numbers on the lower left squares.
- Then on the far left side you put a number that goes into both numbers.
- You keep on going until the numbers are simplified the most.
- The top first numbers are the smallest fractions you can get. The to find the least common multiple you multiply all the left numbers and all the numbers on top.
- To find the greateset common factor you multiply all the numbers on the left side.
