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 22,313,305, 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 | 22,313,305 | |
| -1 | -22,313,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,313,305.
Example:
1 x 22,313,305 = 22,313,305
and
-1 x -22,313,305 = 22,313,305
Notice both answers equal 22,313,305
With that explanation out of the way, let's continue. Next, we take the number 22,313,305 and divide it by 2:
22,313,305 ÷ 2 = 11,156,652.5
If the quotient is a whole number, then 2 and 11,156,652.5 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 | 22,313,305 | |
| -1 | -22,313,305 |
Now, we try dividing 22,313,305 by 3:
22,313,305 ÷ 3 = 7,437,768.3333
If the quotient is a whole number, then 3 and 7,437,768.3333 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 | 22,313,305 | |
| -1 | -22,313,305 |
Let's try dividing by 4:
22,313,305 ÷ 4 = 5,578,326.25
If the quotient is a whole number, then 4 and 5,578,326.25 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 | 22,313,305 | |
| -1 | 22,313,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 83 | 415 | 581 | 2,905 | 7,681 | 38,405 | 53,767 | 268,835 | 637,523 | 3,187,615 | 4,462,661 | 22,313,305 |
| -1 | -5 | -7 | -35 | -83 | -415 | -581 | -2,905 | -7,681 | -38,405 | -53,767 | -268,835 | -637,523 | -3,187,615 | -4,462,661 | -22,313,305 |
