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 22,713,625, 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 | 22,713,625 | |
| -1 | -22,713,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,713,625.
Example:
1 x 22,713,625 = 22,713,625
and
-1 x -22,713,625 = 22,713,625
Notice both answers equal 22,713,625
With that explanation out of the way, let's continue. Next, we take the number 22,713,625 and divide it by 2:
22,713,625 ÷ 2 = 11,356,812.5
If the quotient is a whole number, then 2 and 11,356,812.5 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 | 22,713,625 | |
| -1 | -22,713,625 |
Now, we try dividing 22,713,625 by 3:
22,713,625 ÷ 3 = 7,571,208.3333
If the quotient is a whole number, then 3 and 7,571,208.3333 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 | 22,713,625 | |
| -1 | -22,713,625 |
Let's try dividing by 4:
22,713,625 ÷ 4 = 5,678,406.25
If the quotient is a whole number, then 4 and 5,678,406.25 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 | 22,713,625 | |
| -1 | 22,713,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,375 | 16,519 | 82,595 | 181,709 | 412,975 | 908,545 | 2,064,875 | 4,542,725 | 22,713,625 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,375 | -16,519 | -82,595 | -181,709 | -412,975 | -908,545 | -2,064,875 | -4,542,725 | -22,713,625 |
