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 85,232,135, 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 | 85,232,135 | |
| -1 | -85,232,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 85,232,135.
Example:
1 x 85,232,135 = 85,232,135
and
-1 x -85,232,135 = 85,232,135
Notice both answers equal 85,232,135
With that explanation out of the way, let's continue. Next, we take the number 85,232,135 and divide it by 2:
85,232,135 ÷ 2 = 42,616,067.5
If the quotient is a whole number, then 2 and 42,616,067.5 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 | 85,232,135 | |
| -1 | -85,232,135 |
Now, we try dividing 85,232,135 by 3:
85,232,135 ÷ 3 = 28,410,711.6667
If the quotient is a whole number, then 3 and 28,410,711.6667 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 | 85,232,135 | |
| -1 | -85,232,135 |
Let's try dividing by 4:
85,232,135 ÷ 4 = 21,308,033.75
If the quotient is a whole number, then 4 and 21,308,033.75 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 | 85,232,135 | |
| -1 | 85,232,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 391 | 1,955 | 43,597 | 217,985 | 741,149 | 1,002,731 | 3,705,745 | 5,013,655 | 17,046,427 | 85,232,135 |
| -1 | -5 | -17 | -23 | -85 | -115 | -391 | -1,955 | -43,597 | -217,985 | -741,149 | -1,002,731 | -3,705,745 | -5,013,655 | -17,046,427 | -85,232,135 |
