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 732,704,809, 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 | 732,704,809 | |
| -1 | -732,704,809 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 732,704,809.
Example:
1 x 732,704,809 = 732,704,809
and
-1 x -732,704,809 = 732,704,809
Notice both answers equal 732,704,809
With that explanation out of the way, let's continue. Next, we take the number 732,704,809 and divide it by 2:
732,704,809 ÷ 2 = 366,352,404.5
If the quotient is a whole number, then 2 and 366,352,404.5 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 | 732,704,809 | |
| -1 | -732,704,809 |
Now, we try dividing 732,704,809 by 3:
732,704,809 ÷ 3 = 244,234,936.3333
If the quotient is a whole number, then 3 and 244,234,936.3333 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 | 732,704,809 | |
| -1 | -732,704,809 |
Let's try dividing by 4:
732,704,809 ÷ 4 = 183,176,202.25
If the quotient is a whole number, then 4 and 183,176,202.25 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 | 732,704,809 | |
| -1 | 732,704,809 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 41 | 589 | 779 | 1,271 | 24,149 | 30,341 | 576,479 | 940,571 | 1,243,981 | 17,870,849 | 23,635,639 | 38,563,411 | 732,704,809 |
| -1 | -19 | -31 | -41 | -589 | -779 | -1,271 | -24,149 | -30,341 | -576,479 | -940,571 | -1,243,981 | -17,870,849 | -23,635,639 | -38,563,411 | -732,704,809 |
