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 430,125,163, 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 | 430,125,163 | |
| -1 | -430,125,163 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 430,125,163.
Example:
1 x 430,125,163 = 430,125,163
and
-1 x -430,125,163 = 430,125,163
Notice both answers equal 430,125,163
With that explanation out of the way, let's continue. Next, we take the number 430,125,163 and divide it by 2:
430,125,163 ÷ 2 = 215,062,581.5
If the quotient is a whole number, then 2 and 215,062,581.5 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 | 430,125,163 | |
| -1 | -430,125,163 |
Now, we try dividing 430,125,163 by 3:
430,125,163 ÷ 3 = 143,375,054.3333
If the quotient is a whole number, then 3 and 143,375,054.3333 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 | 430,125,163 | |
| -1 | -430,125,163 |
Let's try dividing by 4:
430,125,163 ÷ 4 = 107,531,290.75
If the quotient is a whole number, then 4 and 107,531,290.75 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 | 430,125,163 | |
| -1 | 430,125,163 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 89 | 767 | 1,157 | 5,251 | 6,301 | 68,263 | 81,913 | 371,759 | 560,789 | 4,832,867 | 7,290,257 | 33,086,551 | 430,125,163 |
| -1 | -13 | -59 | -89 | -767 | -1,157 | -5,251 | -6,301 | -68,263 | -81,913 | -371,759 | -560,789 | -4,832,867 | -7,290,257 | -33,086,551 | -430,125,163 |
