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 225,024,115, 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 | 225,024,115 | |
| -1 | -225,024,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,024,115.
Example:
1 x 225,024,115 = 225,024,115
and
-1 x -225,024,115 = 225,024,115
Notice both answers equal 225,024,115
With that explanation out of the way, let's continue. Next, we take the number 225,024,115 and divide it by 2:
225,024,115 ÷ 2 = 112,512,057.5
If the quotient is a whole number, then 2 and 112,512,057.5 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 | 225,024,115 | |
| -1 | -225,024,115 |
Now, we try dividing 225,024,115 by 3:
225,024,115 ÷ 3 = 75,008,038.3333
If the quotient is a whole number, then 3 and 75,008,038.3333 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 | 225,024,115 | |
| -1 | -225,024,115 |
Let's try dividing by 4:
225,024,115 ÷ 4 = 56,256,028.75
If the quotient is a whole number, then 4 and 56,256,028.75 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 | 225,024,115 | |
| -1 | 225,024,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 211 | 263 | 811 | 1,055 | 1,315 | 4,055 | 55,493 | 171,121 | 213,293 | 277,465 | 855,605 | 1,066,465 | 45,004,823 | 225,024,115 |
| -1 | -5 | -211 | -263 | -811 | -1,055 | -1,315 | -4,055 | -55,493 | -171,121 | -213,293 | -277,465 | -855,605 | -1,066,465 | -45,004,823 | -225,024,115 |
