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 717,540,229, 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 | 717,540,229 | |
| -1 | -717,540,229 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 717,540,229.
Example:
1 x 717,540,229 = 717,540,229
and
-1 x -717,540,229 = 717,540,229
Notice both answers equal 717,540,229
With that explanation out of the way, let's continue. Next, we take the number 717,540,229 and divide it by 2:
717,540,229 ÷ 2 = 358,770,114.5
If the quotient is a whole number, then 2 and 358,770,114.5 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 | 717,540,229 | |
| -1 | -717,540,229 |
Now, we try dividing 717,540,229 by 3:
717,540,229 ÷ 3 = 239,180,076.3333
If the quotient is a whole number, then 3 and 239,180,076.3333 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 | 717,540,229 | |
| -1 | -717,540,229 |
Let's try dividing by 4:
717,540,229 ÷ 4 = 179,385,057.25
If the quotient is a whole number, then 4 and 179,385,057.25 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 | 717,540,229 | |
| -1 | 717,540,229 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 83 | 217 | 581 | 2,573 | 18,011 | 39,839 | 278,873 | 1,235,009 | 3,306,637 | 8,645,063 | 23,146,459 | 102,505,747 | 717,540,229 |
| -1 | -7 | -31 | -83 | -217 | -581 | -2,573 | -18,011 | -39,839 | -278,873 | -1,235,009 | -3,306,637 | -8,645,063 | -23,146,459 | -102,505,747 | -717,540,229 |
