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 430,433,399, 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 | 430,433,399 | |
| -1 | -430,433,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 430,433,399.
Example:
1 x 430,433,399 = 430,433,399
and
-1 x -430,433,399 = 430,433,399
Notice both answers equal 430,433,399
With that explanation out of the way, let's continue. Next, we take the number 430,433,399 and divide it by 2:
430,433,399 ÷ 2 = 215,216,699.5
If the quotient is a whole number, then 2 and 215,216,699.5 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 | 430,433,399 | |
| -1 | -430,433,399 |
Now, we try dividing 430,433,399 by 3:
430,433,399 ÷ 3 = 143,477,799.6667
If the quotient is a whole number, then 3 and 143,477,799.6667 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 | 430,433,399 | |
| -1 | -430,433,399 |
Let's try dividing by 4:
430,433,399 ÷ 4 = 107,608,349.75
If the quotient is a whole number, then 4 and 107,608,349.75 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 | 430,433,399 | |
| -1 | 430,433,399 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 319 | 797 | 1,693 | 8,767 | 18,623 | 23,113 | 49,097 | 254,243 | 540,067 | 1,349,321 | 14,842,531 | 39,130,309 | 430,433,399 |
| -1 | -11 | -29 | -319 | -797 | -1,693 | -8,767 | -18,623 | -23,113 | -49,097 | -254,243 | -540,067 | -1,349,321 | -14,842,531 | -39,130,309 | -430,433,399 |
