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 726,582,635, 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 | 726,582,635 | |
| -1 | -726,582,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 726,582,635.
Example:
1 x 726,582,635 = 726,582,635
and
-1 x -726,582,635 = 726,582,635
Notice both answers equal 726,582,635
With that explanation out of the way, let's continue. Next, we take the number 726,582,635 and divide it by 2:
726,582,635 ÷ 2 = 363,291,317.5
If the quotient is a whole number, then 2 and 363,291,317.5 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 | 726,582,635 | |
| -1 | -726,582,635 |
Now, we try dividing 726,582,635 by 3:
726,582,635 ÷ 3 = 242,194,211.6667
If the quotient is a whole number, then 3 and 242,194,211.6667 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 | 726,582,635 | |
| -1 | -726,582,635 |
Let's try dividing by 4:
726,582,635 ÷ 4 = 181,645,658.75
If the quotient is a whole number, then 4 and 181,645,658.75 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 | 726,582,635 | |
| -1 | 726,582,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 47 | 85 | 235 | 799 | 3,995 | 181,873 | 909,365 | 3,091,841 | 8,548,031 | 15,459,205 | 42,740,155 | 145,316,527 | 726,582,635 |
| -1 | -5 | -17 | -47 | -85 | -235 | -799 | -3,995 | -181,873 | -909,365 | -3,091,841 | -8,548,031 | -15,459,205 | -42,740,155 | -145,316,527 | -726,582,635 |
