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 88,539,731, 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 | 88,539,731 | |
| -1 | -88,539,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,539,731.
Example:
1 x 88,539,731 = 88,539,731
and
-1 x -88,539,731 = 88,539,731
Notice both answers equal 88,539,731
With that explanation out of the way, let's continue. Next, we take the number 88,539,731 and divide it by 2:
88,539,731 ÷ 2 = 44,269,865.5
If the quotient is a whole number, then 2 and 44,269,865.5 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 | 88,539,731 | |
| -1 | -88,539,731 |
Now, we try dividing 88,539,731 by 3:
88,539,731 ÷ 3 = 29,513,243.6667
If the quotient is a whole number, then 3 and 29,513,243.6667 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 | 88,539,731 | |
| -1 | -88,539,731 |
Let's try dividing by 4:
88,539,731 ÷ 4 = 22,134,932.75
If the quotient is a whole number, then 4 and 22,134,932.75 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 | 88,539,731 | |
| -1 | 88,539,731 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 101 | 427 | 707 | 2,053 | 6,161 | 14,371 | 43,127 | 125,233 | 207,353 | 876,631 | 1,451,471 | 12,648,533 | 88,539,731 |
| -1 | -7 | -61 | -101 | -427 | -707 | -2,053 | -6,161 | -14,371 | -43,127 | -125,233 | -207,353 | -876,631 | -1,451,471 | -12,648,533 | -88,539,731 |
