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 22,112,105, 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 | 22,112,105 | |
| -1 | -22,112,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,112,105.
Example:
1 x 22,112,105 = 22,112,105
and
-1 x -22,112,105 = 22,112,105
Notice both answers equal 22,112,105
With that explanation out of the way, let's continue. Next, we take the number 22,112,105 and divide it by 2:
22,112,105 ÷ 2 = 11,056,052.5
If the quotient is a whole number, then 2 and 11,056,052.5 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 | 22,112,105 | |
| -1 | -22,112,105 |
Now, we try dividing 22,112,105 by 3:
22,112,105 ÷ 3 = 7,370,701.6667
If the quotient is a whole number, then 3 and 7,370,701.6667 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 | 22,112,105 | |
| -1 | -22,112,105 |
Let's try dividing by 4:
22,112,105 ÷ 4 = 5,528,026.25
If the quotient is a whole number, then 4 and 5,528,026.25 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 | 22,112,105 | |
| -1 | 22,112,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 43 | 95 | 215 | 817 | 4,085 | 5,413 | 27,065 | 102,847 | 232,759 | 514,235 | 1,163,795 | 4,422,421 | 22,112,105 |
| -1 | -5 | -19 | -43 | -95 | -215 | -817 | -4,085 | -5,413 | -27,065 | -102,847 | -232,759 | -514,235 | -1,163,795 | -4,422,421 | -22,112,105 |
