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 22,100,117, 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 | 22,100,117 | |
| -1 | -22,100,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,100,117.
Example:
1 x 22,100,117 = 22,100,117
and
-1 x -22,100,117 = 22,100,117
Notice both answers equal 22,100,117
With that explanation out of the way, let's continue. Next, we take the number 22,100,117 and divide it by 2:
22,100,117 ÷ 2 = 11,050,058.5
If the quotient is a whole number, then 2 and 11,050,058.5 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 | 22,100,117 | |
| -1 | -22,100,117 |
Now, we try dividing 22,100,117 by 3:
22,100,117 ÷ 3 = 7,366,705.6667
If the quotient is a whole number, then 3 and 7,366,705.6667 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 | 22,100,117 | |
| -1 | -22,100,117 |
Let's try dividing by 4:
22,100,117 ÷ 4 = 5,525,029.25
If the quotient is a whole number, then 4 and 5,525,029.25 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 | 22,100,117 | |
| -1 | 22,100,117 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 31 | 61 | 377 | 403 | 793 | 899 | 961 | 1,769 | 1,891 | 11,687 | 12,493 | 22,997 | 24,583 | 27,869 | 54,839 | 58,621 | 362,297 | 712,907 | 762,073 | 1,700,009 | 22,100,117 |
| -1 | -13 | -29 | -31 | -61 | -377 | -403 | -793 | -899 | -961 | -1,769 | -1,891 | -11,687 | -12,493 | -22,997 | -24,583 | -27,869 | -54,839 | -58,621 | -362,297 | -712,907 | -762,073 | -1,700,009 | -22,100,117 |
