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 71,468,789, 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 | 71,468,789 | |
| -1 | -71,468,789 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,468,789.
Example:
1 x 71,468,789 = 71,468,789
and
-1 x -71,468,789 = 71,468,789
Notice both answers equal 71,468,789
With that explanation out of the way, let's continue. Next, we take the number 71,468,789 and divide it by 2:
71,468,789 ÷ 2 = 35,734,394.5
If the quotient is a whole number, then 2 and 35,734,394.5 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 | 71,468,789 | |
| -1 | -71,468,789 |
Now, we try dividing 71,468,789 by 3:
71,468,789 ÷ 3 = 23,822,929.6667
If the quotient is a whole number, then 3 and 23,822,929.6667 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 | 71,468,789 | |
| -1 | -71,468,789 |
Let's try dividing by 4:
71,468,789 ÷ 4 = 17,867,197.25
If the quotient is a whole number, then 4 and 17,867,197.25 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 | 71,468,789 | |
| -1 | 71,468,789 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 233 | 1,511 | 1,631 | 6,757 | 10,577 | 43,819 | 47,299 | 306,733 | 352,063 | 2,464,441 | 10,209,827 | 71,468,789 |
| -1 | -7 | -29 | -203 | -233 | -1,511 | -1,631 | -6,757 | -10,577 | -43,819 | -47,299 | -306,733 | -352,063 | -2,464,441 | -10,209,827 | -71,468,789 |
