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 83,802,715, 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 | 83,802,715 | |
| -1 | -83,802,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,802,715.
Example:
1 x 83,802,715 = 83,802,715
and
-1 x -83,802,715 = 83,802,715
Notice both answers equal 83,802,715
With that explanation out of the way, let's continue. Next, we take the number 83,802,715 and divide it by 2:
83,802,715 ÷ 2 = 41,901,357.5
If the quotient is a whole number, then 2 and 41,901,357.5 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 | 83,802,715 | |
| -1 | -83,802,715 |
Now, we try dividing 83,802,715 by 3:
83,802,715 ÷ 3 = 27,934,238.3333
If the quotient is a whole number, then 3 and 27,934,238.3333 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 | 83,802,715 | |
| -1 | -83,802,715 |
Let's try dividing by 4:
83,802,715 ÷ 4 = 20,950,678.75
If the quotient is a whole number, then 4 and 20,950,678.75 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 | 83,802,715 | |
| -1 | 83,802,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 61 | 295 | 305 | 3,599 | 4,657 | 17,995 | 23,285 | 274,763 | 284,077 | 1,373,815 | 1,420,385 | 16,760,543 | 83,802,715 |
| -1 | -5 | -59 | -61 | -295 | -305 | -3,599 | -4,657 | -17,995 | -23,285 | -274,763 | -284,077 | -1,373,815 | -1,420,385 | -16,760,543 | -83,802,715 |
