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 726,770,447, 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 | 726,770,447 | |
| -1 | -726,770,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 726,770,447.
Example:
1 x 726,770,447 = 726,770,447
and
-1 x -726,770,447 = 726,770,447
Notice both answers equal 726,770,447
With that explanation out of the way, let's continue. Next, we take the number 726,770,447 and divide it by 2:
726,770,447 ÷ 2 = 363,385,223.5
If the quotient is a whole number, then 2 and 363,385,223.5 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 | 726,770,447 | |
| -1 | -726,770,447 |
Now, we try dividing 726,770,447 by 3:
726,770,447 ÷ 3 = 242,256,815.6667
If the quotient is a whole number, then 3 and 242,256,815.6667 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 | 726,770,447 | |
| -1 | -726,770,447 |
Let's try dividing by 4:
726,770,447 ÷ 4 = 181,692,611.75
If the quotient is a whole number, then 4 and 181,692,611.75 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 | 726,770,447 | |
| -1 | 726,770,447 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 101 | 611 | 1,313 | 4,747 | 11,777 | 61,711 | 153,101 | 553,519 | 1,189,477 | 7,195,747 | 15,463,201 | 55,905,419 | 726,770,447 |
| -1 | -13 | -47 | -101 | -611 | -1,313 | -4,747 | -11,777 | -61,711 | -153,101 | -553,519 | -1,189,477 | -7,195,747 | -15,463,201 | -55,905,419 | -726,770,447 |
