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 22,208,183, 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 | 22,208,183 | |
| -1 | -22,208,183 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,208,183.
Example:
1 x 22,208,183 = 22,208,183
and
-1 x -22,208,183 = 22,208,183
Notice both answers equal 22,208,183
With that explanation out of the way, let's continue. Next, we take the number 22,208,183 and divide it by 2:
22,208,183 ÷ 2 = 11,104,091.5
If the quotient is a whole number, then 2 and 11,104,091.5 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 | 22,208,183 | |
| -1 | -22,208,183 |
Now, we try dividing 22,208,183 by 3:
22,208,183 ÷ 3 = 7,402,727.6667
If the quotient is a whole number, then 3 and 7,402,727.6667 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 | 22,208,183 | |
| -1 | -22,208,183 |
Let's try dividing by 4:
22,208,183 ÷ 4 = 5,552,045.75
If the quotient is a whole number, then 4 and 5,552,045.75 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 | 22,208,183 | |
| -1 | 22,208,183 |
If you did it right, you will end up with this table:
| 1 | 31 | 41 | 101 | 173 | 1,271 | 3,131 | 4,141 | 5,363 | 7,093 | 17,473 | 128,371 | 219,883 | 541,663 | 716,393 | 22,208,183 |
| -1 | -31 | -41 | -101 | -173 | -1,271 | -3,131 | -4,141 | -5,363 | -7,093 | -17,473 | -128,371 | -219,883 | -541,663 | -716,393 | -22,208,183 |
