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 68,431,685, 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 | 68,431,685 | |
| -1 | -68,431,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,431,685.
Example:
1 x 68,431,685 = 68,431,685
and
-1 x -68,431,685 = 68,431,685
Notice both answers equal 68,431,685
With that explanation out of the way, let's continue. Next, we take the number 68,431,685 and divide it by 2:
68,431,685 ÷ 2 = 34,215,842.5
If the quotient is a whole number, then 2 and 34,215,842.5 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 | 68,431,685 | |
| -1 | -68,431,685 |
Now, we try dividing 68,431,685 by 3:
68,431,685 ÷ 3 = 22,810,561.6667
If the quotient is a whole number, then 3 and 22,810,561.6667 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 | 68,431,685 | |
| -1 | -68,431,685 |
Let's try dividing by 4:
68,431,685 ÷ 4 = 17,107,921.25
If the quotient is a whole number, then 4 and 17,107,921.25 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 | 68,431,685 | |
| -1 | 68,431,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 49 | 185 | 245 | 259 | 1,295 | 1,813 | 7,549 | 9,065 | 37,745 | 52,843 | 264,215 | 279,313 | 369,901 | 1,396,565 | 1,849,505 | 1,955,191 | 9,775,955 | 13,686,337 | 68,431,685 |
| -1 | -5 | -7 | -35 | -37 | -49 | -185 | -245 | -259 | -1,295 | -1,813 | -7,549 | -9,065 | -37,745 | -52,843 | -264,215 | -279,313 | -369,901 | -1,396,565 | -1,849,505 | -1,955,191 | -9,775,955 | -13,686,337 | -68,431,685 |
