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 22,470,305, 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 | 22,470,305 | |
| -1 | -22,470,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,470,305.
Example:
1 x 22,470,305 = 22,470,305
and
-1 x -22,470,305 = 22,470,305
Notice both answers equal 22,470,305
With that explanation out of the way, let's continue. Next, we take the number 22,470,305 and divide it by 2:
22,470,305 ÷ 2 = 11,235,152.5
If the quotient is a whole number, then 2 and 11,235,152.5 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 | 22,470,305 | |
| -1 | -22,470,305 |
Now, we try dividing 22,470,305 by 3:
22,470,305 ÷ 3 = 7,490,101.6667
If the quotient is a whole number, then 3 and 7,490,101.6667 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 | 22,470,305 | |
| -1 | -22,470,305 |
Let's try dividing by 4:
22,470,305 ÷ 4 = 5,617,576.25
If the quotient is a whole number, then 4 and 5,617,576.25 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 | 22,470,305 | |
| -1 | 22,470,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 121 | 143 | 605 | 715 | 1,573 | 2,857 | 7,865 | 14,285 | 31,427 | 37,141 | 157,135 | 185,705 | 345,697 | 408,551 | 1,728,485 | 2,042,755 | 4,494,061 | 22,470,305 |
| -1 | -5 | -11 | -13 | -55 | -65 | -121 | -143 | -605 | -715 | -1,573 | -2,857 | -7,865 | -14,285 | -31,427 | -37,141 | -157,135 | -185,705 | -345,697 | -408,551 | -1,728,485 | -2,042,755 | -4,494,061 | -22,470,305 |
