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 22,502,623, 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 | 22,502,623 | |
| -1 | -22,502,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,502,623.
Example:
1 x 22,502,623 = 22,502,623
and
-1 x -22,502,623 = 22,502,623
Notice both answers equal 22,502,623
With that explanation out of the way, let's continue. Next, we take the number 22,502,623 and divide it by 2:
22,502,623 ÷ 2 = 11,251,311.5
If the quotient is a whole number, then 2 and 11,251,311.5 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 | 22,502,623 | |
| -1 | -22,502,623 |
Now, we try dividing 22,502,623 by 3:
22,502,623 ÷ 3 = 7,500,874.3333
If the quotient is a whole number, then 3 and 7,500,874.3333 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 | 22,502,623 | |
| -1 | -22,502,623 |
Let's try dividing by 4:
22,502,623 ÷ 4 = 5,625,655.75
If the quotient is a whole number, then 4 and 5,625,655.75 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 | 22,502,623 | |
| -1 | 22,502,623 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 37 | 143 | 407 | 481 | 4,253 | 5,291 | 46,783 | 55,289 | 157,361 | 608,179 | 1,730,971 | 2,045,693 | 22,502,623 |
| -1 | -11 | -13 | -37 | -143 | -407 | -481 | -4,253 | -5,291 | -46,783 | -55,289 | -157,361 | -608,179 | -1,730,971 | -2,045,693 | -22,502,623 |
