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 225,613,255, 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 | 225,613,255 | |
| -1 | -225,613,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,613,255.
Example:
1 x 225,613,255 = 225,613,255
and
-1 x -225,613,255 = 225,613,255
Notice both answers equal 225,613,255
With that explanation out of the way, let's continue. Next, we take the number 225,613,255 and divide it by 2:
225,613,255 ÷ 2 = 112,806,627.5
If the quotient is a whole number, then 2 and 112,806,627.5 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 | 225,613,255 | |
| -1 | -225,613,255 |
Now, we try dividing 225,613,255 by 3:
225,613,255 ÷ 3 = 75,204,418.3333
If the quotient is a whole number, then 3 and 75,204,418.3333 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 | 225,613,255 | |
| -1 | -225,613,255 |
Let's try dividing by 4:
225,613,255 ÷ 4 = 56,403,313.75
If the quotient is a whole number, then 4 and 56,403,313.75 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 | 225,613,255 | |
| -1 | 225,613,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 443 | 2,215 | 3,101 | 14,551 | 15,505 | 72,755 | 101,857 | 509,285 | 6,446,093 | 32,230,465 | 45,122,651 | 225,613,255 |
| -1 | -5 | -7 | -35 | -443 | -2,215 | -3,101 | -14,551 | -15,505 | -72,755 | -101,857 | -509,285 | -6,446,093 | -32,230,465 | -45,122,651 | -225,613,255 |
