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 430,310,165, 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 | 430,310,165 | |
| -1 | -430,310,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 430,310,165.
Example:
1 x 430,310,165 = 430,310,165
and
-1 x -430,310,165 = 430,310,165
Notice both answers equal 430,310,165
With that explanation out of the way, let's continue. Next, we take the number 430,310,165 and divide it by 2:
430,310,165 ÷ 2 = 215,155,082.5
If the quotient is a whole number, then 2 and 215,155,082.5 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 | 430,310,165 | |
| -1 | -430,310,165 |
Now, we try dividing 430,310,165 by 3:
430,310,165 ÷ 3 = 143,436,721.6667
If the quotient is a whole number, then 3 and 143,436,721.6667 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 | 430,310,165 | |
| -1 | -430,310,165 |
Let's try dividing by 4:
430,310,165 ÷ 4 = 107,577,541.25
If the quotient is a whole number, then 4 and 107,577,541.25 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 | 430,310,165 | |
| -1 | 430,310,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 305 | 967 | 1,459 | 4,835 | 7,295 | 58,987 | 88,999 | 294,935 | 444,995 | 1,410,853 | 7,054,265 | 86,062,033 | 430,310,165 |
| -1 | -5 | -61 | -305 | -967 | -1,459 | -4,835 | -7,295 | -58,987 | -88,999 | -294,935 | -444,995 | -1,410,853 | -7,054,265 | -86,062,033 | -430,310,165 |
