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 40,032,223, 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 | 40,032,223 | |
| -1 | -40,032,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,032,223.
Example:
1 x 40,032,223 = 40,032,223
and
-1 x -40,032,223 = 40,032,223
Notice both answers equal 40,032,223
With that explanation out of the way, let's continue. Next, we take the number 40,032,223 and divide it by 2:
40,032,223 ÷ 2 = 20,016,111.5
If the quotient is a whole number, then 2 and 20,016,111.5 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 | 40,032,223 | |
| -1 | -40,032,223 |
Now, we try dividing 40,032,223 by 3:
40,032,223 ÷ 3 = 13,344,074.3333
If the quotient is a whole number, then 3 and 13,344,074.3333 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 | 40,032,223 | |
| -1 | -40,032,223 |
Let's try dividing by 4:
40,032,223 ÷ 4 = 10,008,055.75
If the quotient is a whole number, then 4 and 10,008,055.75 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 | 40,032,223 | |
| -1 | 40,032,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 79 | 553 | 869 | 6,083 | 6,581 | 46,067 | 72,391 | 506,737 | 519,899 | 3,639,293 | 5,718,889 | 40,032,223 |
| -1 | -7 | -11 | -77 | -79 | -553 | -869 | -6,083 | -6,581 | -46,067 | -72,391 | -506,737 | -519,899 | -3,639,293 | -5,718,889 | -40,032,223 |
