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 22,836,815, 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 | 22,836,815 | |
| -1 | -22,836,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,836,815.
Example:
1 x 22,836,815 = 22,836,815
and
-1 x -22,836,815 = 22,836,815
Notice both answers equal 22,836,815
With that explanation out of the way, let's continue. Next, we take the number 22,836,815 and divide it by 2:
22,836,815 ÷ 2 = 11,418,407.5
If the quotient is a whole number, then 2 and 11,418,407.5 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 | 22,836,815 | |
| -1 | -22,836,815 |
Now, we try dividing 22,836,815 by 3:
22,836,815 ÷ 3 = 7,612,271.6667
If the quotient is a whole number, then 3 and 7,612,271.6667 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 | 22,836,815 | |
| -1 | -22,836,815 |
Let's try dividing by 4:
22,836,815 ÷ 4 = 5,709,203.75
If the quotient is a whole number, then 4 and 5,709,203.75 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 | 22,836,815 | |
| -1 | 22,836,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 349 | 569 | 1,745 | 2,845 | 8,027 | 13,087 | 40,135 | 65,435 | 198,581 | 992,905 | 4,567,363 | 22,836,815 |
| -1 | -5 | -23 | -115 | -349 | -569 | -1,745 | -2,845 | -8,027 | -13,087 | -40,135 | -65,435 | -198,581 | -992,905 | -4,567,363 | -22,836,815 |
