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 514,681,609, 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 | 514,681,609 | |
| -1 | -514,681,609 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 514,681,609.
Example:
1 x 514,681,609 = 514,681,609
and
-1 x -514,681,609 = 514,681,609
Notice both answers equal 514,681,609
With that explanation out of the way, let's continue. Next, we take the number 514,681,609 and divide it by 2:
514,681,609 ÷ 2 = 257,340,804.5
If the quotient is a whole number, then 2 and 257,340,804.5 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 | 514,681,609 | |
| -1 | -514,681,609 |
Now, we try dividing 514,681,609 by 3:
514,681,609 ÷ 3 = 171,560,536.3333
If the quotient is a whole number, then 3 and 171,560,536.3333 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 | 514,681,609 | |
| -1 | -514,681,609 |
Let's try dividing by 4:
514,681,609 ÷ 4 = 128,670,402.25
If the quotient is a whole number, then 4 and 128,670,402.25 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 | 514,681,609 | |
| -1 | 514,681,609 |
If you did it right, you will end up with this table:
| 1 | 13 | 73 | 197 | 949 | 2,561 | 2,753 | 14,381 | 35,789 | 186,953 | 200,969 | 542,341 | 2,612,597 | 7,050,433 | 39,590,893 | 514,681,609 |
| -1 | -13 | -73 | -197 | -949 | -2,561 | -2,753 | -14,381 | -35,789 | -186,953 | -200,969 | -542,341 | -2,612,597 | -7,050,433 | -39,590,893 | -514,681,609 |
