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 88,935,979, 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 | 88,935,979 | |
| -1 | -88,935,979 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,935,979.
Example:
1 x 88,935,979 = 88,935,979
and
-1 x -88,935,979 = 88,935,979
Notice both answers equal 88,935,979
With that explanation out of the way, let's continue. Next, we take the number 88,935,979 and divide it by 2:
88,935,979 ÷ 2 = 44,467,989.5
If the quotient is a whole number, then 2 and 44,467,989.5 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 | 88,935,979 | |
| -1 | -88,935,979 |
Now, we try dividing 88,935,979 by 3:
88,935,979 ÷ 3 = 29,645,326.3333
If the quotient is a whole number, then 3 and 29,645,326.3333 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 | 88,935,979 | |
| -1 | -88,935,979 |
Let's try dividing by 4:
88,935,979 ÷ 4 = 22,233,994.75
If the quotient is a whole number, then 4 and 22,233,994.75 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 | 88,935,979 | |
| -1 | 88,935,979 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 181 | 209 | 1,991 | 2,351 | 3,439 | 25,861 | 37,829 | 44,669 | 425,531 | 491,359 | 4,680,841 | 8,085,089 | 88,935,979 |
| -1 | -11 | -19 | -181 | -209 | -1,991 | -2,351 | -3,439 | -25,861 | -37,829 | -44,669 | -425,531 | -491,359 | -4,680,841 | -8,085,089 | -88,935,979 |
