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 129,606,455, 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 | 129,606,455 | |
| -1 | -129,606,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 129,606,455.
Example:
1 x 129,606,455 = 129,606,455
and
-1 x -129,606,455 = 129,606,455
Notice both answers equal 129,606,455
With that explanation out of the way, let's continue. Next, we take the number 129,606,455 and divide it by 2:
129,606,455 ÷ 2 = 64,803,227.5
If the quotient is a whole number, then 2 and 64,803,227.5 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 | 129,606,455 | |
| -1 | -129,606,455 |
Now, we try dividing 129,606,455 by 3:
129,606,455 ÷ 3 = 43,202,151.6667
If the quotient is a whole number, then 3 and 43,202,151.6667 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 | 129,606,455 | |
| -1 | -129,606,455 |
Let's try dividing by 4:
129,606,455 ÷ 4 = 32,401,613.75
If the quotient is a whole number, then 4 and 32,401,613.75 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 | 129,606,455 | |
| -1 | 129,606,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,061 | 2,221 | 5,305 | 11,105 | 11,671 | 24,431 | 58,355 | 122,155 | 2,356,481 | 11,782,405 | 25,921,291 | 129,606,455 |
| -1 | -5 | -11 | -55 | -1,061 | -2,221 | -5,305 | -11,105 | -11,671 | -24,431 | -58,355 | -122,155 | -2,356,481 | -11,782,405 | -25,921,291 | -129,606,455 |
