What Are the Factors of 408?

The factors of 408 are 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408.

This is how to find the factors of 408. First, every number is divisible by itself and 1.


  1. Try 1. 1 x 408 = 408, so put these into our factor list.
    1...408

  2. Take 2. 2 x 204 = 408, which means we add these to our factor list.
    12...204408

  3. Now take 3. 3 x 136 = 408, so now we put these in our list of factors.
    123...136204408

  4. Next try 4. 4 x 102 = 408, so we add these to our list of factors.
    1234...102136204408

  5. Now try 5... nope! 408/5 isn't a whole number. So we skip 5.

  6. Try 6. 6 x 68 = 408, which means we add these to our factor list.
    12346...68102136204408

  7. Take 7... no. 408/7 isn't a whole number. So we skip 7.

  8. Now take 8. 8 x 51 = 408, so we add these to our list of factors.
    123468...5168102136204408

  9. Next try 9... nope! 408/9 isn't a whole number. So we skip 9.

  10. Now try 10... no good. 408/10 isn't a whole number. So we skip 10.

  11. Try 11... no. 408/11 isn't a whole number. So we skip 11.

  12. Take 12. 12 x 34 = 408, so we add these to our list of factors.
    12346812...345168102136204408

  13. Now take 13... nope! 408/13 isn't a whole number. So we skip 13.

  14. Next try 14... no good. 408/14 isn't a whole number. So we skip 14.

  15. Now try 15... no. 408/15 isn't a whole number. So we skip 15.

  16. Try 16... no luck. 408/16 isn't a whole number. So we skip 16.

  17. Take 17. 17 x 24 = 408, so put these into our factor list.
    1234681217...24345168102136204408

  18. Now take 18... no good. 408/18 isn't a whole number. So we skip 18.

  19. Next try 19... no. 408/19 isn't a whole number. So we skip 19.

  20. Now try 20... no luck. 408/20 isn't a whole number. So we skip 20.

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