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 430,206,403, 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 | 430,206,403 | |
| -1 | -430,206,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 430,206,403.
Example:
1 x 430,206,403 = 430,206,403
and
-1 x -430,206,403 = 430,206,403
Notice both answers equal 430,206,403
With that explanation out of the way, let's continue. Next, we take the number 430,206,403 and divide it by 2:
430,206,403 ÷ 2 = 215,103,201.5
If the quotient is a whole number, then 2 and 215,103,201.5 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 | 430,206,403 | |
| -1 | -430,206,403 |
Now, we try dividing 430,206,403 by 3:
430,206,403 ÷ 3 = 143,402,134.3333
If the quotient is a whole number, then 3 and 143,402,134.3333 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 | 430,206,403 | |
| -1 | -430,206,403 |
Let's try dividing by 4:
430,206,403 ÷ 4 = 107,551,600.75
If the quotient is a whole number, then 4 and 107,551,600.75 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 | 430,206,403 | |
| -1 | 430,206,403 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 659 | 3,491 | 7,249 | 11,203 | 38,401 | 59,347 | 123,233 | 652,817 | 2,300,569 | 25,306,259 | 39,109,673 | 430,206,403 |
| -1 | -11 | -17 | -187 | -659 | -3,491 | -7,249 | -11,203 | -38,401 | -59,347 | -123,233 | -652,817 | -2,300,569 | -25,306,259 | -39,109,673 | -430,206,403 |
