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 22,506,305, 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 | 22,506,305 | |
| -1 | -22,506,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,506,305.
Example:
1 x 22,506,305 = 22,506,305
and
-1 x -22,506,305 = 22,506,305
Notice both answers equal 22,506,305
With that explanation out of the way, let's continue. Next, we take the number 22,506,305 and divide it by 2:
22,506,305 ÷ 2 = 11,253,152.5
If the quotient is a whole number, then 2 and 11,253,152.5 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 | 22,506,305 | |
| -1 | -22,506,305 |
Now, we try dividing 22,506,305 by 3:
22,506,305 ÷ 3 = 7,502,101.6667
If the quotient is a whole number, then 3 and 7,502,101.6667 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 | 22,506,305 | |
| -1 | -22,506,305 |
Let's try dividing by 4:
22,506,305 ÷ 4 = 5,626,576.25
If the quotient is a whole number, then 4 and 5,626,576.25 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 | 22,506,305 | |
| -1 | 22,506,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 67 | 115 | 127 | 335 | 529 | 635 | 1,541 | 2,645 | 2,921 | 7,705 | 8,509 | 14,605 | 35,443 | 42,545 | 67,183 | 177,215 | 195,707 | 335,915 | 978,535 | 4,501,261 | 22,506,305 |
| -1 | -5 | -23 | -67 | -115 | -127 | -335 | -529 | -635 | -1,541 | -2,645 | -2,921 | -7,705 | -8,509 | -14,605 | -35,443 | -42,545 | -67,183 | -177,215 | -195,707 | -335,915 | -978,535 | -4,501,261 | -22,506,305 |
