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 431,353,511, 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 | 431,353,511 | |
| -1 | -431,353,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 431,353,511.
Example:
1 x 431,353,511 = 431,353,511
and
-1 x -431,353,511 = 431,353,511
Notice both answers equal 431,353,511
With that explanation out of the way, let's continue. Next, we take the number 431,353,511 and divide it by 2:
431,353,511 ÷ 2 = 215,676,755.5
If the quotient is a whole number, then 2 and 215,676,755.5 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 | 431,353,511 | |
| -1 | -431,353,511 |
Now, we try dividing 431,353,511 by 3:
431,353,511 ÷ 3 = 143,784,503.6667
If the quotient is a whole number, then 3 and 143,784,503.6667 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 | 431,353,511 | |
| -1 | -431,353,511 |
Let's try dividing by 4:
431,353,511 ÷ 4 = 107,838,377.75
If the quotient is a whole number, then 4 and 107,838,377.75 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 | 431,353,511 | |
| -1 | 431,353,511 |
If you did it right, you will end up with this table:
| 1 | 29 | 37 | 43 | 1,073 | 1,247 | 1,591 | 9,349 | 46,139 | 271,121 | 345,913 | 402,007 | 10,031,477 | 11,658,203 | 14,874,259 | 431,353,511 |
| -1 | -29 | -37 | -43 | -1,073 | -1,247 | -1,591 | -9,349 | -46,139 | -271,121 | -345,913 | -402,007 | -10,031,477 | -11,658,203 | -14,874,259 | -431,353,511 |
