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 23,156,413, 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 | 23,156,413 | |
| -1 | -23,156,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,156,413.
Example:
1 x 23,156,413 = 23,156,413
and
-1 x -23,156,413 = 23,156,413
Notice both answers equal 23,156,413
With that explanation out of the way, let's continue. Next, we take the number 23,156,413 and divide it by 2:
23,156,413 ÷ 2 = 11,578,206.5
If the quotient is a whole number, then 2 and 11,578,206.5 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 | 23,156,413 | |
| -1 | -23,156,413 |
Now, we try dividing 23,156,413 by 3:
23,156,413 ÷ 3 = 7,718,804.3333
If the quotient is a whole number, then 3 and 7,718,804.3333 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 | 23,156,413 | |
| -1 | -23,156,413 |
Let's try dividing by 4:
23,156,413 ÷ 4 = 5,789,103.25
If the quotient is a whole number, then 4 and 5,789,103.25 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 | 23,156,413 | |
| -1 | 23,156,413 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 37 | 203 | 259 | 1,073 | 3,083 | 7,511 | 21,581 | 89,407 | 114,071 | 625,849 | 798,497 | 3,308,059 | 23,156,413 |
| -1 | -7 | -29 | -37 | -203 | -259 | -1,073 | -3,083 | -7,511 | -21,581 | -89,407 | -114,071 | -625,849 | -798,497 | -3,308,059 | -23,156,413 |
