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 22,896,797, 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 | 22,896,797 | |
| -1 | -22,896,797 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,896,797.
Example:
1 x 22,896,797 = 22,896,797
and
-1 x -22,896,797 = 22,896,797
Notice both answers equal 22,896,797
With that explanation out of the way, let's continue. Next, we take the number 22,896,797 and divide it by 2:
22,896,797 ÷ 2 = 11,448,398.5
If the quotient is a whole number, then 2 and 11,448,398.5 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 | 22,896,797 | |
| -1 | -22,896,797 |
Now, we try dividing 22,896,797 by 3:
22,896,797 ÷ 3 = 7,632,265.6667
If the quotient is a whole number, then 3 and 7,632,265.6667 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 | 22,896,797 | |
| -1 | -22,896,797 |
Let's try dividing by 4:
22,896,797 ÷ 4 = 5,724,199.25
If the quotient is a whole number, then 4 and 5,724,199.25 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 | 22,896,797 | |
| -1 | 22,896,797 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 103 | 721 | 1,133 | 2,887 | 7,931 | 20,209 | 31,757 | 222,299 | 297,361 | 2,081,527 | 3,270,971 | 22,896,797 |
| -1 | -7 | -11 | -77 | -103 | -721 | -1,133 | -2,887 | -7,931 | -20,209 | -31,757 | -222,299 | -297,361 | -2,081,527 | -3,270,971 | -22,896,797 |
