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 83,090,035, 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 | 83,090,035 | |
| -1 | -83,090,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,090,035.
Example:
1 x 83,090,035 = 83,090,035
and
-1 x -83,090,035 = 83,090,035
Notice both answers equal 83,090,035
With that explanation out of the way, let's continue. Next, we take the number 83,090,035 and divide it by 2:
83,090,035 ÷ 2 = 41,545,017.5
If the quotient is a whole number, then 2 and 41,545,017.5 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 | 83,090,035 | |
| -1 | -83,090,035 |
Now, we try dividing 83,090,035 by 3:
83,090,035 ÷ 3 = 27,696,678.3333
If the quotient is a whole number, then 3 and 27,696,678.3333 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 | 83,090,035 | |
| -1 | -83,090,035 |
Let's try dividing by 4:
83,090,035 ÷ 4 = 20,772,508.75
If the quotient is a whole number, then 4 and 20,772,508.75 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 | 83,090,035 | |
| -1 | 83,090,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 48,449 | 242,245 | 339,143 | 1,695,715 | 2,374,001 | 11,870,005 | 16,618,007 | 83,090,035 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -48,449 | -242,245 | -339,143 | -1,695,715 | -2,374,001 | -11,870,005 | -16,618,007 | -83,090,035 |
