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 726,404,485, 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 | 726,404,485 | |
| -1 | -726,404,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 726,404,485.
Example:
1 x 726,404,485 = 726,404,485
and
-1 x -726,404,485 = 726,404,485
Notice both answers equal 726,404,485
With that explanation out of the way, let's continue. Next, we take the number 726,404,485 and divide it by 2:
726,404,485 ÷ 2 = 363,202,242.5
If the quotient is a whole number, then 2 and 363,202,242.5 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 | 726,404,485 | |
| -1 | -726,404,485 |
Now, we try dividing 726,404,485 by 3:
726,404,485 ÷ 3 = 242,134,828.3333
If the quotient is a whole number, then 3 and 242,134,828.3333 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 | 726,404,485 | |
| -1 | -726,404,485 |
Let's try dividing by 4:
726,404,485 ÷ 4 = 181,601,121.25
If the quotient is a whole number, then 4 and 181,601,121.25 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 | 726,404,485 | |
| -1 | 726,404,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 53 | 95 | 265 | 1,007 | 5,035 | 144,271 | 721,355 | 2,741,149 | 7,646,363 | 13,705,745 | 38,231,815 | 145,280,897 | 726,404,485 |
| -1 | -5 | -19 | -53 | -95 | -265 | -1,007 | -5,035 | -144,271 | -721,355 | -2,741,149 | -7,646,363 | -13,705,745 | -38,231,815 | -145,280,897 | -726,404,485 |
