Write the number you are finding the factors of at the top of your paper.
Start with 1 and the number itself.
Write 1 × the number, because 1 is a factor of every number.Leave space between the numbers so you can add more factor pairs as you go.
Move inward by counting up from 2 and checking if it multiplies evenly into the number.
Each time you find a number that multiplies evenly, write the matching factor pair.
Keep checking numbers in order, working inward from both sides.
Stop when you reach consecutive numbers (or when the numbers meet or cross).
This means there are no more factors.Circle or list all the numbers you wrote.
These are all the factors of the number.
