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 81,793,795, 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 | 81,793,795 | |
| -1 | -81,793,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 81,793,795.
Example:
1 x 81,793,795 = 81,793,795
and
-1 x -81,793,795 = 81,793,795
Notice both answers equal 81,793,795
With that explanation out of the way, let's continue. Next, we take the number 81,793,795 and divide it by 2:
81,793,795 ÷ 2 = 40,896,897.5
If the quotient is a whole number, then 2 and 40,896,897.5 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 | 81,793,795 | |
| -1 | -81,793,795 |
Now, we try dividing 81,793,795 by 3:
81,793,795 ÷ 3 = 27,264,598.3333
If the quotient is a whole number, then 3 and 27,264,598.3333 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 | 81,793,795 | |
| -1 | -81,793,795 |
Let's try dividing by 4:
81,793,795 ÷ 4 = 20,448,448.75
If the quotient is a whole number, then 4 and 20,448,448.75 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 | 81,793,795 | |
| -1 | 81,793,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 137 | 485 | 685 | 1,231 | 6,155 | 13,289 | 66,445 | 119,407 | 168,647 | 597,035 | 843,235 | 16,358,759 | 81,793,795 |
| -1 | -5 | -97 | -137 | -485 | -685 | -1,231 | -6,155 | -13,289 | -66,445 | -119,407 | -168,647 | -597,035 | -843,235 | -16,358,759 | -81,793,795 |
