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 22,018,927, 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 | 22,018,927 | |
| -1 | -22,018,927 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,018,927.
Example:
1 x 22,018,927 = 22,018,927
and
-1 x -22,018,927 = 22,018,927
Notice both answers equal 22,018,927
With that explanation out of the way, let's continue. Next, we take the number 22,018,927 and divide it by 2:
22,018,927 ÷ 2 = 11,009,463.5
If the quotient is a whole number, then 2 and 11,009,463.5 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 | 22,018,927 | |
| -1 | -22,018,927 |
Now, we try dividing 22,018,927 by 3:
22,018,927 ÷ 3 = 7,339,642.3333
If the quotient is a whole number, then 3 and 7,339,642.3333 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 | 22,018,927 | |
| -1 | -22,018,927 |
Let's try dividing by 4:
22,018,927 ÷ 4 = 5,504,731.75
If the quotient is a whole number, then 4 and 5,504,731.75 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 | 22,018,927 | |
| -1 | 22,018,927 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 41 | 119 | 287 | 697 | 4,513 | 4,879 | 31,591 | 76,721 | 185,033 | 537,047 | 1,295,231 | 3,145,561 | 22,018,927 |
| -1 | -7 | -17 | -41 | -119 | -287 | -697 | -4,513 | -4,879 | -31,591 | -76,721 | -185,033 | -537,047 | -1,295,231 | -3,145,561 | -22,018,927 |
