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 88,211,785, 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 | 88,211,785 | |
| -1 | -88,211,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 88,211,785.
Example:
1 x 88,211,785 = 88,211,785
and
-1 x -88,211,785 = 88,211,785
Notice both answers equal 88,211,785
With that explanation out of the way, let's continue. Next, we take the number 88,211,785 and divide it by 2:
88,211,785 ÷ 2 = 44,105,892.5
If the quotient is a whole number, then 2 and 44,105,892.5 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 | 88,211,785 | |
| -1 | -88,211,785 |
Now, we try dividing 88,211,785 by 3:
88,211,785 ÷ 3 = 29,403,928.3333
If the quotient is a whole number, then 3 and 29,403,928.3333 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 | 88,211,785 | |
| -1 | -88,211,785 |
Let's try dividing by 4:
88,211,785 ÷ 4 = 22,052,946.25
If the quotient is a whole number, then 4 and 22,052,946.25 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 | 88,211,785 | |
| -1 | 88,211,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 59 | 115 | 295 | 1,357 | 6,785 | 13,001 | 65,005 | 299,023 | 767,059 | 1,495,115 | 3,835,295 | 17,642,357 | 88,211,785 |
| -1 | -5 | -23 | -59 | -115 | -295 | -1,357 | -6,785 | -13,001 | -65,005 | -299,023 | -767,059 | -1,495,115 | -3,835,295 | -17,642,357 | -88,211,785 |
