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 711,660,355, 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 | 711,660,355 | |
| -1 | -711,660,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 711,660,355.
Example:
1 x 711,660,355 = 711,660,355
and
-1 x -711,660,355 = 711,660,355
Notice both answers equal 711,660,355
With that explanation out of the way, let's continue. Next, we take the number 711,660,355 and divide it by 2:
711,660,355 ÷ 2 = 355,830,177.5
If the quotient is a whole number, then 2 and 355,830,177.5 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 | 711,660,355 | |
| -1 | -711,660,355 |
Now, we try dividing 711,660,355 by 3:
711,660,355 ÷ 3 = 237,220,118.3333
If the quotient is a whole number, then 3 and 237,220,118.3333 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 | 711,660,355 | |
| -1 | -711,660,355 |
Let's try dividing by 4:
711,660,355 ÷ 4 = 177,915,088.75
If the quotient is a whole number, then 4 and 177,915,088.75 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 | 711,660,355 | |
| -1 | 711,660,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 353 | 1,765 | 2,471 | 12,355 | 57,601 | 288,005 | 403,207 | 2,016,035 | 20,333,153 | 101,665,765 | 142,332,071 | 711,660,355 |
| -1 | -5 | -7 | -35 | -353 | -1,765 | -2,471 | -12,355 | -57,601 | -288,005 | -403,207 | -2,016,035 | -20,333,153 | -101,665,765 | -142,332,071 | -711,660,355 |
