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 66,558,023, 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 | 66,558,023 | |
| -1 | -66,558,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,558,023.
Example:
1 x 66,558,023 = 66,558,023
and
-1 x -66,558,023 = 66,558,023
Notice both answers equal 66,558,023
With that explanation out of the way, let's continue. Next, we take the number 66,558,023 and divide it by 2:
66,558,023 ÷ 2 = 33,279,011.5
If the quotient is a whole number, then 2 and 33,279,011.5 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 | 66,558,023 | |
| -1 | -66,558,023 |
Now, we try dividing 66,558,023 by 3:
66,558,023 ÷ 3 = 22,186,007.6667
If the quotient is a whole number, then 3 and 22,186,007.6667 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 | 66,558,023 | |
| -1 | -66,558,023 |
Let's try dividing by 4:
66,558,023 ÷ 4 = 16,639,505.75
If the quotient is a whole number, then 4 and 16,639,505.75 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 | 66,558,023 | |
| -1 | 66,558,023 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 43 | 49 | 217 | 301 | 1,019 | 1,333 | 1,519 | 2,107 | 7,133 | 9,331 | 31,589 | 43,817 | 49,931 | 65,317 | 221,123 | 306,719 | 1,358,327 | 1,547,861 | 2,147,033 | 9,508,289 | 66,558,023 |
| -1 | -7 | -31 | -43 | -49 | -217 | -301 | -1,019 | -1,333 | -1,519 | -2,107 | -7,133 | -9,331 | -31,589 | -43,817 | -49,931 | -65,317 | -221,123 | -306,719 | -1,358,327 | -1,547,861 | -2,147,033 | -9,508,289 | -66,558,023 |
