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 22,023,905, 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 | 22,023,905 | |
| -1 | -22,023,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,023,905.
Example:
1 x 22,023,905 = 22,023,905
and
-1 x -22,023,905 = 22,023,905
Notice both answers equal 22,023,905
With that explanation out of the way, let's continue. Next, we take the number 22,023,905 and divide it by 2:
22,023,905 ÷ 2 = 11,011,952.5
If the quotient is a whole number, then 2 and 11,011,952.5 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 | 22,023,905 | |
| -1 | -22,023,905 |
Now, we try dividing 22,023,905 by 3:
22,023,905 ÷ 3 = 7,341,301.6667
If the quotient is a whole number, then 3 and 7,341,301.6667 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 | 22,023,905 | |
| -1 | -22,023,905 |
Let's try dividing by 4:
22,023,905 ÷ 4 = 5,505,976.25
If the quotient is a whole number, then 4 and 5,505,976.25 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 | 22,023,905 | |
| -1 | 22,023,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 67 | 145 | 335 | 1,943 | 2,267 | 9,715 | 11,335 | 65,743 | 151,889 | 328,715 | 759,445 | 4,404,781 | 22,023,905 |
| -1 | -5 | -29 | -67 | -145 | -335 | -1,943 | -2,267 | -9,715 | -11,335 | -65,743 | -151,889 | -328,715 | -759,445 | -4,404,781 | -22,023,905 |
