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 707,502,349, 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 | 707,502,349 | |
| -1 | -707,502,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 707,502,349.
Example:
1 x 707,502,349 = 707,502,349
and
-1 x -707,502,349 = 707,502,349
Notice both answers equal 707,502,349
With that explanation out of the way, let's continue. Next, we take the number 707,502,349 and divide it by 2:
707,502,349 ÷ 2 = 353,751,174.5
If the quotient is a whole number, then 2 and 353,751,174.5 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 | 707,502,349 | |
| -1 | -707,502,349 |
Now, we try dividing 707,502,349 by 3:
707,502,349 ÷ 3 = 235,834,116.3333
If the quotient is a whole number, then 3 and 235,834,116.3333 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 | 707,502,349 | |
| -1 | -707,502,349 |
Let's try dividing by 4:
707,502,349 ÷ 4 = 176,875,587.25
If the quotient is a whole number, then 4 and 176,875,587.25 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 | 707,502,349 | |
| -1 | 707,502,349 |
If you did it right, you will end up with this table:
| 1 | 43 | 73 | 263 | 857 | 3,139 | 11,309 | 19,199 | 36,851 | 62,561 | 225,391 | 825,557 | 2,690,123 | 9,691,813 | 16,453,543 | 707,502,349 |
| -1 | -43 | -73 | -263 | -857 | -3,139 | -11,309 | -19,199 | -36,851 | -62,561 | -225,391 | -825,557 | -2,690,123 | -9,691,813 | -16,453,543 | -707,502,349 |
