  2. Take 2... no good. 441/2 isn't a whole number. So we skip 2.

  3. Now take 3. 3 x 147 = 441, so now we put these in our list of factors.
    13...147441

  4. Next try 4... no luck. 441/4 isn't a whole number. So we skip 4.

  5. Now try 5... nope! 441/5 isn't a whole number. So we skip 5.

  6. Try 6... no good. 441/6 isn't a whole number. So we skip 6.

  7. Take 7. 7 x 63 = 441, so now we put these in our list of factors.
    137...63147441

  8. Now take 8... no luck. 441/8 isn't a whole number. So we skip 8.

  9. Next try 9. 9 x 49 = 441, so put these into our factor list.
    1379...4963147441

  10. Now try 10... no good. 441/10 isn't a whole number. So we skip 10.

  11. Try 11... no. 441/11 isn't a whole number. So we skip 11.
