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 88,690,085, 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 | 88,690,085 | |
| -1 | -88,690,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,690,085.
Example:
1 x 88,690,085 = 88,690,085
and
-1 x -88,690,085 = 88,690,085
Notice both answers equal 88,690,085
With that explanation out of the way, let's continue. Next, we take the number 88,690,085 and divide it by 2:
88,690,085 ÷ 2 = 44,345,042.5
If the quotient is a whole number, then 2 and 44,345,042.5 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 | 88,690,085 | |
| -1 | -88,690,085 |
Now, we try dividing 88,690,085 by 3:
88,690,085 ÷ 3 = 29,563,361.6667
If the quotient is a whole number, then 3 and 29,563,361.6667 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 | 88,690,085 | |
| -1 | -88,690,085 |
Let's try dividing by 4:
88,690,085 ÷ 4 = 22,172,521.25
If the quotient is a whole number, then 4 and 22,172,521.25 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 | 88,690,085 | |
| -1 | 88,690,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 157 | 785 | 1,727 | 8,635 | 10,271 | 51,355 | 112,981 | 564,905 | 1,612,547 | 8,062,735 | 17,738,017 | 88,690,085 |
| -1 | -5 | -11 | -55 | -157 | -785 | -1,727 | -8,635 | -10,271 | -51,355 | -112,981 | -564,905 | -1,612,547 | -8,062,735 | -17,738,017 | -88,690,085 |
