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 83,804,815, 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 | 83,804,815 | |
| -1 | -83,804,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,804,815.
Example:
1 x 83,804,815 = 83,804,815
and
-1 x -83,804,815 = 83,804,815
Notice both answers equal 83,804,815
With that explanation out of the way, let's continue. Next, we take the number 83,804,815 and divide it by 2:
83,804,815 ÷ 2 = 41,902,407.5
If the quotient is a whole number, then 2 and 41,902,407.5 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 | 83,804,815 | |
| -1 | -83,804,815 |
Now, we try dividing 83,804,815 by 3:
83,804,815 ÷ 3 = 27,934,938.3333
If the quotient is a whole number, then 3 and 27,934,938.3333 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 | 83,804,815 | |
| -1 | -83,804,815 |
Let's try dividing by 4:
83,804,815 ÷ 4 = 20,951,203.75
If the quotient is a whole number, then 4 and 20,951,203.75 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 | 83,804,815 | |
| -1 | 83,804,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 85 | 185 | 629 | 3,145 | 26,647 | 133,235 | 452,999 | 985,939 | 2,264,995 | 4,929,695 | 16,760,963 | 83,804,815 |
| -1 | -5 | -17 | -37 | -85 | -185 | -629 | -3,145 | -26,647 | -133,235 | -452,999 | -985,939 | -2,264,995 | -4,929,695 | -16,760,963 | -83,804,815 |
