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 430,131,215, 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 | 430,131,215 | |
| -1 | -430,131,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 430,131,215.
Example:
1 x 430,131,215 = 430,131,215
and
-1 x -430,131,215 = 430,131,215
Notice both answers equal 430,131,215
With that explanation out of the way, let's continue. Next, we take the number 430,131,215 and divide it by 2:
430,131,215 ÷ 2 = 215,065,607.5
If the quotient is a whole number, then 2 and 215,065,607.5 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 | 430,131,215 | |
| -1 | -430,131,215 |
Now, we try dividing 430,131,215 by 3:
430,131,215 ÷ 3 = 143,377,071.6667
If the quotient is a whole number, then 3 and 143,377,071.6667 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 | 430,131,215 | |
| -1 | -430,131,215 |
Let's try dividing by 4:
430,131,215 ÷ 4 = 107,532,803.75
If the quotient is a whole number, then 4 and 107,532,803.75 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 | 430,131,215 | |
| -1 | 430,131,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 89 | 95 | 445 | 1,691 | 8,455 | 50,873 | 254,365 | 966,587 | 4,527,697 | 4,832,935 | 22,638,485 | 86,026,243 | 430,131,215 |
| -1 | -5 | -19 | -89 | -95 | -445 | -1,691 | -8,455 | -50,873 | -254,365 | -966,587 | -4,527,697 | -4,832,935 | -22,638,485 | -86,026,243 | -430,131,215 |
