What Are the Factors of 20?

The factors of 20 are 1, 2, 4, 5, 10, 20.

Calcating the factors of 20 is straightforward. Take 20 and the number 1. Those are the first two factors.


  1. Try 1. 1 x 20 = 20, so put these into our factor list.
    1...20

  2. Take 2. 2 x 10 = 20, which means we add these to our factor list.
    12...1020

  3. Now take 3... no. 20/3 isn't a whole number. So we skip 3.

  4. Next try 4. 4 x 5 = 20, so we add these to our list of factors.
    124...51020

  5. Now, since we don't have any more numbers to try, we're done!
