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 88,737,887, 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 | 88,737,887 | |
| -1 | -88,737,887 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,737,887.
Example:
1 x 88,737,887 = 88,737,887
and
-1 x -88,737,887 = 88,737,887
Notice both answers equal 88,737,887
With that explanation out of the way, let's continue. Next, we take the number 88,737,887 and divide it by 2:
88,737,887 ÷ 2 = 44,368,943.5
If the quotient is a whole number, then 2 and 44,368,943.5 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 | 88,737,887 | |
| -1 | -88,737,887 |
Now, we try dividing 88,737,887 by 3:
88,737,887 ÷ 3 = 29,579,295.6667
If the quotient is a whole number, then 3 and 29,579,295.6667 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 | 88,737,887 | |
| -1 | -88,737,887 |
Let's try dividing by 4:
88,737,887 ÷ 4 = 22,184,471.75
If the quotient is a whole number, then 4 and 22,184,471.75 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 | 88,737,887 | |
| -1 | 88,737,887 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 241 | 1,687 | 2,287 | 5,543 | 16,009 | 38,801 | 52,601 | 368,207 | 551,167 | 3,858,169 | 12,676,841 | 88,737,887 |
| -1 | -7 | -23 | -161 | -241 | -1,687 | -2,287 | -5,543 | -16,009 | -38,801 | -52,601 | -368,207 | -551,167 | -3,858,169 | -12,676,841 | -88,737,887 |
