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 66,664,129, 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 | 66,664,129 | |
| -1 | -66,664,129 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,664,129.
Example:
1 x 66,664,129 = 66,664,129
and
-1 x -66,664,129 = 66,664,129
Notice both answers equal 66,664,129
With that explanation out of the way, let's continue. Next, we take the number 66,664,129 and divide it by 2:
66,664,129 ÷ 2 = 33,332,064.5
If the quotient is a whole number, then 2 and 33,332,064.5 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 | 66,664,129 | |
| -1 | -66,664,129 |
Now, we try dividing 66,664,129 by 3:
66,664,129 ÷ 3 = 22,221,376.3333
If the quotient is a whole number, then 3 and 22,221,376.3333 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 | 66,664,129 | |
| -1 | -66,664,129 |
Let's try dividing by 4:
66,664,129 ÷ 4 = 16,666,032.25
If the quotient is a whole number, then 4 and 16,666,032.25 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 | 66,664,129 | |
| -1 | 66,664,129 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 307 | 463 | 469 | 2,149 | 3,241 | 20,569 | 31,021 | 142,141 | 143,983 | 217,147 | 994,987 | 9,523,447 | 66,664,129 |
| -1 | -7 | -67 | -307 | -463 | -469 | -2,149 | -3,241 | -20,569 | -31,021 | -142,141 | -143,983 | -217,147 | -994,987 | -9,523,447 | -66,664,129 |
