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 430,254,605, 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 | 430,254,605 | |
| -1 | -430,254,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 430,254,605.
Example:
1 x 430,254,605 = 430,254,605
and
-1 x -430,254,605 = 430,254,605
Notice both answers equal 430,254,605
With that explanation out of the way, let's continue. Next, we take the number 430,254,605 and divide it by 2:
430,254,605 ÷ 2 = 215,127,302.5
If the quotient is a whole number, then 2 and 215,127,302.5 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 | 430,254,605 | |
| -1 | -430,254,605 |
Now, we try dividing 430,254,605 by 3:
430,254,605 ÷ 3 = 143,418,201.6667
If the quotient is a whole number, then 3 and 143,418,201.6667 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 | 430,254,605 | |
| -1 | -430,254,605 |
Let's try dividing by 4:
430,254,605 ÷ 4 = 107,563,651.25
If the quotient is a whole number, then 4 and 107,563,651.25 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 | 430,254,605 | |
| -1 | 430,254,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 691 | 3,455 | 7,601 | 11,321 | 38,005 | 56,605 | 124,531 | 622,655 | 7,822,811 | 39,114,055 | 86,050,921 | 430,254,605 |
| -1 | -5 | -11 | -55 | -691 | -3,455 | -7,601 | -11,321 | -38,005 | -56,605 | -124,531 | -622,655 | -7,822,811 | -39,114,055 | -86,050,921 | -430,254,605 |
