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 22,135,505, 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 | 22,135,505 | |
| -1 | -22,135,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,135,505.
Example:
1 x 22,135,505 = 22,135,505
and
-1 x -22,135,505 = 22,135,505
Notice both answers equal 22,135,505
With that explanation out of the way, let's continue. Next, we take the number 22,135,505 and divide it by 2:
22,135,505 ÷ 2 = 11,067,752.5
If the quotient is a whole number, then 2 and 11,067,752.5 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 | 22,135,505 | |
| -1 | -22,135,505 |
Now, we try dividing 22,135,505 by 3:
22,135,505 ÷ 3 = 7,378,501.6667
If the quotient is a whole number, then 3 and 7,378,501.6667 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 | 22,135,505 | |
| -1 | -22,135,505 |
Let's try dividing by 4:
22,135,505 ÷ 4 = 5,533,876.25
If the quotient is a whole number, then 4 and 5,533,876.25 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 | 22,135,505 | |
| -1 | 22,135,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 12,907 | 64,535 | 90,349 | 451,745 | 632,443 | 3,162,215 | 4,427,101 | 22,135,505 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -12,907 | -64,535 | -90,349 | -451,745 | -632,443 | -3,162,215 | -4,427,101 | -22,135,505 |
