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 85,702,535, 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 | 85,702,535 | |
| -1 | -85,702,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,702,535.
Example:
1 x 85,702,535 = 85,702,535
and
-1 x -85,702,535 = 85,702,535
Notice both answers equal 85,702,535
With that explanation out of the way, let's continue. Next, we take the number 85,702,535 and divide it by 2:
85,702,535 ÷ 2 = 42,851,267.5
If the quotient is a whole number, then 2 and 42,851,267.5 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 | 85,702,535 | |
| -1 | -85,702,535 |
Now, we try dividing 85,702,535 by 3:
85,702,535 ÷ 3 = 28,567,511.6667
If the quotient is a whole number, then 3 and 28,567,511.6667 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 | 85,702,535 | |
| -1 | -85,702,535 |
Let's try dividing by 4:
85,702,535 ÷ 4 = 21,425,633.75
If the quotient is a whole number, then 4 and 21,425,633.75 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 | 85,702,535 | |
| -1 | 85,702,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 139 | 317 | 389 | 695 | 1,585 | 1,945 | 44,063 | 54,071 | 123,313 | 220,315 | 270,355 | 616,565 | 17,140,507 | 85,702,535 |
| -1 | -5 | -139 | -317 | -389 | -695 | -1,585 | -1,945 | -44,063 | -54,071 | -123,313 | -220,315 | -270,355 | -616,565 | -17,140,507 | -85,702,535 |
