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 22,705,423, 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 | 22,705,423 | |
| -1 | -22,705,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,705,423.
Example:
1 x 22,705,423 = 22,705,423
and
-1 x -22,705,423 = 22,705,423
Notice both answers equal 22,705,423
With that explanation out of the way, let's continue. Next, we take the number 22,705,423 and divide it by 2:
22,705,423 ÷ 2 = 11,352,711.5
If the quotient is a whole number, then 2 and 11,352,711.5 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 | 22,705,423 | |
| -1 | -22,705,423 |
Now, we try dividing 22,705,423 by 3:
22,705,423 ÷ 3 = 7,568,474.3333
If the quotient is a whole number, then 3 and 7,568,474.3333 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 | 22,705,423 | |
| -1 | -22,705,423 |
Let's try dividing by 4:
22,705,423 ÷ 4 = 5,676,355.75
If the quotient is a whole number, then 4 and 5,676,355.75 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 | 22,705,423 | |
| -1 | 22,705,423 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 103 | 403 | 547 | 1,339 | 3,193 | 7,111 | 16,957 | 41,509 | 56,341 | 220,441 | 732,433 | 1,746,571 | 22,705,423 |
| -1 | -13 | -31 | -103 | -403 | -547 | -1,339 | -3,193 | -7,111 | -16,957 | -41,509 | -56,341 | -220,441 | -732,433 | -1,746,571 | -22,705,423 |
