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 225,055,457, 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 | 225,055,457 | |
| -1 | -225,055,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,055,457.
Example:
1 x 225,055,457 = 225,055,457
and
-1 x -225,055,457 = 225,055,457
Notice both answers equal 225,055,457
With that explanation out of the way, let's continue. Next, we take the number 225,055,457 and divide it by 2:
225,055,457 ÷ 2 = 112,527,728.5
If the quotient is a whole number, then 2 and 112,527,728.5 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 | 225,055,457 | |
| -1 | -225,055,457 |
Now, we try dividing 225,055,457 by 3:
225,055,457 ÷ 3 = 75,018,485.6667
If the quotient is a whole number, then 3 and 75,018,485.6667 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 | 225,055,457 | |
| -1 | -225,055,457 |
Let's try dividing by 4:
225,055,457 ÷ 4 = 56,263,864.25
If the quotient is a whole number, then 4 and 56,263,864.25 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 | 225,055,457 | |
| -1 | 225,055,457 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 89 | 319 | 979 | 2,581 | 7,927 | 28,391 | 87,197 | 229,883 | 705,503 | 2,528,713 | 7,760,533 | 20,459,587 | 225,055,457 |
| -1 | -11 | -29 | -89 | -319 | -979 | -2,581 | -7,927 | -28,391 | -87,197 | -229,883 | -705,503 | -2,528,713 | -7,760,533 | -20,459,587 | -225,055,457 |
