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 22,815,865, 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 | 22,815,865 | |
| -1 | -22,815,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,815,865.
Example:
1 x 22,815,865 = 22,815,865
and
-1 x -22,815,865 = 22,815,865
Notice both answers equal 22,815,865
With that explanation out of the way, let's continue. Next, we take the number 22,815,865 and divide it by 2:
22,815,865 ÷ 2 = 11,407,932.5
If the quotient is a whole number, then 2 and 11,407,932.5 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 | 22,815,865 | |
| -1 | -22,815,865 |
Now, we try dividing 22,815,865 by 3:
22,815,865 ÷ 3 = 7,605,288.3333
If the quotient is a whole number, then 3 and 7,605,288.3333 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 | 22,815,865 | |
| -1 | -22,815,865 |
Let's try dividing by 4:
22,815,865 ÷ 4 = 5,703,966.25
If the quotient is a whole number, then 4 and 5,703,966.25 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 | 22,815,865 | |
| -1 | 22,815,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 37 | 95 | 185 | 703 | 3,515 | 6,491 | 32,455 | 123,329 | 240,167 | 616,645 | 1,200,835 | 4,563,173 | 22,815,865 |
| -1 | -5 | -19 | -37 | -95 | -185 | -703 | -3,515 | -6,491 | -32,455 | -123,329 | -240,167 | -616,645 | -1,200,835 | -4,563,173 | -22,815,865 |
