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 23,220,995, 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 | 23,220,995 | |
| -1 | -23,220,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,220,995.
Example:
1 x 23,220,995 = 23,220,995
and
-1 x -23,220,995 = 23,220,995
Notice both answers equal 23,220,995
With that explanation out of the way, let's continue. Next, we take the number 23,220,995 and divide it by 2:
23,220,995 ÷ 2 = 11,610,497.5
If the quotient is a whole number, then 2 and 11,610,497.5 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 | 23,220,995 | |
| -1 | -23,220,995 |
Now, we try dividing 23,220,995 by 3:
23,220,995 ÷ 3 = 7,740,331.6667
If the quotient is a whole number, then 3 and 7,740,331.6667 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 | 23,220,995 | |
| -1 | -23,220,995 |
Let's try dividing by 4:
23,220,995 ÷ 4 = 5,805,248.75
If the quotient is a whole number, then 4 and 5,805,248.75 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 | 23,220,995 | |
| -1 | 23,220,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 503 | 1,319 | 2,515 | 3,521 | 6,595 | 9,233 | 17,605 | 46,165 | 663,457 | 3,317,285 | 4,644,199 | 23,220,995 |
| -1 | -5 | -7 | -35 | -503 | -1,319 | -2,515 | -3,521 | -6,595 | -9,233 | -17,605 | -46,165 | -663,457 | -3,317,285 | -4,644,199 | -23,220,995 |
