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 225,244,315, 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 | 225,244,315 | |
| -1 | -225,244,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,244,315.
Example:
1 x 225,244,315 = 225,244,315
and
-1 x -225,244,315 = 225,244,315
Notice both answers equal 225,244,315
With that explanation out of the way, let's continue. Next, we take the number 225,244,315 and divide it by 2:
225,244,315 ÷ 2 = 112,622,157.5
If the quotient is a whole number, then 2 and 112,622,157.5 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 | 225,244,315 | |
| -1 | -225,244,315 |
Now, we try dividing 225,244,315 by 3:
225,244,315 ÷ 3 = 75,081,438.3333
If the quotient is a whole number, then 3 and 75,081,438.3333 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 | 225,244,315 | |
| -1 | -225,244,315 |
Let's try dividing by 4:
225,244,315 ÷ 4 = 56,311,078.75
If the quotient is a whole number, then 4 and 56,311,078.75 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 | 225,244,315 | |
| -1 | 225,244,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 439 | 445 | 1,153 | 2,195 | 5,765 | 39,071 | 102,617 | 195,355 | 506,167 | 513,085 | 2,530,835 | 45,048,863 | 225,244,315 |
| -1 | -5 | -89 | -439 | -445 | -1,153 | -2,195 | -5,765 | -39,071 | -102,617 | -195,355 | -506,167 | -513,085 | -2,530,835 | -45,048,863 | -225,244,315 |
