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 67,468,471, 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 | 67,468,471 | |
| -1 | -67,468,471 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,468,471.
Example:
1 x 67,468,471 = 67,468,471
and
-1 x -67,468,471 = 67,468,471
Notice both answers equal 67,468,471
With that explanation out of the way, let's continue. Next, we take the number 67,468,471 and divide it by 2:
67,468,471 ÷ 2 = 33,734,235.5
If the quotient is a whole number, then 2 and 33,734,235.5 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 | 67,468,471 | |
| -1 | -67,468,471 |
Now, we try dividing 67,468,471 by 3:
67,468,471 ÷ 3 = 22,489,490.3333
If the quotient is a whole number, then 3 and 22,489,490.3333 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 | 67,468,471 | |
| -1 | -67,468,471 |
Let's try dividing by 4:
67,468,471 ÷ 4 = 16,867,117.75
If the quotient is a whole number, then 4 and 16,867,117.75 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 | 67,468,471 | |
| -1 | 67,468,471 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 163 | 203 | 1,141 | 2,039 | 4,727 | 14,273 | 33,089 | 59,131 | 332,357 | 413,917 | 2,326,499 | 9,638,353 | 67,468,471 |
| -1 | -7 | -29 | -163 | -203 | -1,141 | -2,039 | -4,727 | -14,273 | -33,089 | -59,131 | -332,357 | -413,917 | -2,326,499 | -9,638,353 | -67,468,471 |
