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 83,746,105, 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 | 83,746,105 | |
| -1 | -83,746,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,746,105.
Example:
1 x 83,746,105 = 83,746,105
and
-1 x -83,746,105 = 83,746,105
Notice both answers equal 83,746,105
With that explanation out of the way, let's continue. Next, we take the number 83,746,105 and divide it by 2:
83,746,105 ÷ 2 = 41,873,052.5
If the quotient is a whole number, then 2 and 41,873,052.5 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 | 83,746,105 | |
| -1 | -83,746,105 |
Now, we try dividing 83,746,105 by 3:
83,746,105 ÷ 3 = 27,915,368.3333
If the quotient is a whole number, then 3 and 27,915,368.3333 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 | 83,746,105 | |
| -1 | -83,746,105 |
Let's try dividing by 4:
83,746,105 ÷ 4 = 20,936,526.25
If the quotient is a whole number, then 4 and 20,936,526.25 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 | 83,746,105 | |
| -1 | 83,746,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 821 | 887 | 4,105 | 4,435 | 18,883 | 20,401 | 94,415 | 102,005 | 728,227 | 3,641,135 | 16,749,221 | 83,746,105 |
| -1 | -5 | -23 | -115 | -821 | -887 | -4,105 | -4,435 | -18,883 | -20,401 | -94,415 | -102,005 | -728,227 | -3,641,135 | -16,749,221 | -83,746,105 |
