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 726,134,537, 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 | 726,134,537 | |
| -1 | -726,134,537 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 726,134,537.
Example:
1 x 726,134,537 = 726,134,537
and
-1 x -726,134,537 = 726,134,537
Notice both answers equal 726,134,537
With that explanation out of the way, let's continue. Next, we take the number 726,134,537 and divide it by 2:
726,134,537 ÷ 2 = 363,067,268.5
If the quotient is a whole number, then 2 and 363,067,268.5 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 | 726,134,537 | |
| -1 | -726,134,537 |
Now, we try dividing 726,134,537 by 3:
726,134,537 ÷ 3 = 242,044,845.6667
If the quotient is a whole number, then 3 and 242,044,845.6667 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 | 726,134,537 | |
| -1 | -726,134,537 |
Let's try dividing by 4:
726,134,537 ÷ 4 = 181,533,634.25
If the quotient is a whole number, then 4 and 181,533,634.25 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 | 726,134,537 | |
| -1 | 726,134,537 |
If you did it right, you will end up with this table:
| 1 | 47 | 71 | 167 | 1,303 | 3,337 | 7,849 | 11,857 | 61,241 | 92,513 | 217,601 | 557,279 | 4,348,111 | 10,227,247 | 15,449,671 | 726,134,537 |
| -1 | -47 | -71 | -167 | -1,303 | -3,337 | -7,849 | -11,857 | -61,241 | -92,513 | -217,601 | -557,279 | -4,348,111 | -10,227,247 | -15,449,671 | -726,134,537 |
