Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 33,440,407, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 33,440,407 | |
| -1 | -33,440,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,440,407.
Example:
1 x 33,440,407 = 33,440,407
and
-1 x -33,440,407 = 33,440,407
Notice both answers equal 33,440,407
With that explanation out of the way, let's continue. Next, we take the number 33,440,407 and divide it by 2:
33,440,407 ÷ 2 = 16,720,203.5
If the quotient is a whole number, then 2 and 16,720,203.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 33,440,407 | |
| -1 | -33,440,407 |
Now, we try dividing 33,440,407 by 3:
33,440,407 ÷ 3 = 11,146,802.3333
If the quotient is a whole number, then 3 and 11,146,802.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 33,440,407 | |
| -1 | -33,440,407 |
Let's try dividing by 4:
33,440,407 ÷ 4 = 8,360,101.75
If the quotient is a whole number, then 4 and 8,360,101.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 33,440,407 | |
| -1 | 33,440,407 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 121 | 143 | 847 | 1,001 | 1,573 | 3,037 | 11,011 | 21,259 | 33,407 | 39,481 | 233,849 | 276,367 | 367,477 | 434,291 | 2,572,339 | 3,040,037 | 4,777,201 | 33,440,407 |
| -1 | -7 | -11 | -13 | -77 | -91 | -121 | -143 | -847 | -1,001 | -1,573 | -3,037 | -11,011 | -21,259 | -33,407 | -39,481 | -233,849 | -276,367 | -367,477 | -434,291 | -2,572,339 | -3,040,037 | -4,777,201 | -33,440,407 |
