What Are the Factors of 123?

The factors of 123 are 1, 3, 41, 123.

This is how to find the factors of 123. 1 and 123 are the first two factors.


  1. Try 1. 1 x 123 = 123, so put these into our factor list.
    1...123

  2. Take 2... no good. 123/2 isn't a whole number. So we skip 2.

  3. Now take 3. 3 x 41 = 123, so now we put these in our list of factors.
    13...41123

  4. Next try 4... no luck. 123/4 isn't a whole number. So we skip 4.

  5. Now try 5... nope! 123/5 isn't a whole number. So we skip 5.

  6. Try 6... no good. 123/6 isn't a whole number. So we skip 6.

  7. Take 7... no. 123/7 isn't a whole number. So we skip 7.

  8. Now take 8... no luck. 123/8 isn't a whole number. So we skip 8.

  9. Next try 9... nope! 123/9 isn't a whole number. So we skip 9.

  10. Now try 10... no good. 123/10 isn't a whole number. So we skip 10.

  11. Try 11... no. 123/11 isn't a whole number. So we skip 11.

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