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 430,010,315, 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 | 430,010,315 | |
| -1 | -430,010,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 430,010,315.
Example:
1 x 430,010,315 = 430,010,315
and
-1 x -430,010,315 = 430,010,315
Notice both answers equal 430,010,315
With that explanation out of the way, let's continue. Next, we take the number 430,010,315 and divide it by 2:
430,010,315 ÷ 2 = 215,005,157.5
If the quotient is a whole number, then 2 and 215,005,157.5 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 | 430,010,315 | |
| -1 | -430,010,315 |
Now, we try dividing 430,010,315 by 3:
430,010,315 ÷ 3 = 143,336,771.6667
If the quotient is a whole number, then 3 and 143,336,771.6667 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 | 430,010,315 | |
| -1 | -430,010,315 |
Let's try dividing by 4:
430,010,315 ÷ 4 = 107,502,578.75
If the quotient is a whole number, then 4 and 107,502,578.75 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 | 430,010,315 | |
| -1 | 430,010,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 337 | 1,685 | 2,359 | 11,795 | 36,457 | 182,285 | 255,199 | 1,275,995 | 12,286,009 | 61,430,045 | 86,002,063 | 430,010,315 |
| -1 | -5 | -7 | -35 | -337 | -1,685 | -2,359 | -11,795 | -36,457 | -182,285 | -255,199 | -1,275,995 | -12,286,009 | -61,430,045 | -86,002,063 | -430,010,315 |
