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 22,126,355, 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 | 22,126,355 | |
| -1 | -22,126,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,126,355.
Example:
1 x 22,126,355 = 22,126,355
and
-1 x -22,126,355 = 22,126,355
Notice both answers equal 22,126,355
With that explanation out of the way, let's continue. Next, we take the number 22,126,355 and divide it by 2:
22,126,355 ÷ 2 = 11,063,177.5
If the quotient is a whole number, then 2 and 11,063,177.5 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 | 22,126,355 | |
| -1 | -22,126,355 |
Now, we try dividing 22,126,355 by 3:
22,126,355 ÷ 3 = 7,375,451.6667
If the quotient is a whole number, then 3 and 7,375,451.6667 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 | 22,126,355 | |
| -1 | -22,126,355 |
Let's try dividing by 4:
22,126,355 ÷ 4 = 5,531,588.75
If the quotient is a whole number, then 4 and 5,531,588.75 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 | 22,126,355 | |
| -1 | 22,126,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 283 | 823 | 1,415 | 4,115 | 5,377 | 15,637 | 26,885 | 78,185 | 232,909 | 1,164,545 | 4,425,271 | 22,126,355 |
| -1 | -5 | -19 | -95 | -283 | -823 | -1,415 | -4,115 | -5,377 | -15,637 | -26,885 | -78,185 | -232,909 | -1,164,545 | -4,425,271 | -22,126,355 |
