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 708,714,307, 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 | 708,714,307 | |
| -1 | -708,714,307 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 708,714,307.
Example:
1 x 708,714,307 = 708,714,307
and
-1 x -708,714,307 = 708,714,307
Notice both answers equal 708,714,307
With that explanation out of the way, let's continue. Next, we take the number 708,714,307 and divide it by 2:
708,714,307 ÷ 2 = 354,357,153.5
If the quotient is a whole number, then 2 and 354,357,153.5 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 | 708,714,307 | |
| -1 | -708,714,307 |
Now, we try dividing 708,714,307 by 3:
708,714,307 ÷ 3 = 236,238,102.3333
If the quotient is a whole number, then 3 and 236,238,102.3333 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 | 708,714,307 | |
| -1 | -708,714,307 |
Let's try dividing by 4:
708,714,307 ÷ 4 = 177,178,576.75
If the quotient is a whole number, then 4 and 177,178,576.75 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 | 708,714,307 | |
| -1 | 708,714,307 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 383 | 2,681 | 7,277 | 13,913 | 50,939 | 97,391 | 264,347 | 1,850,429 | 5,328,679 | 37,300,753 | 101,244,901 | 708,714,307 |
| -1 | -7 | -19 | -133 | -383 | -2,681 | -7,277 | -13,913 | -50,939 | -97,391 | -264,347 | -1,850,429 | -5,328,679 | -37,300,753 | -101,244,901 | -708,714,307 |
