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 65,770,127, 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 | 65,770,127 | |
| -1 | -65,770,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,770,127.
Example:
1 x 65,770,127 = 65,770,127
and
-1 x -65,770,127 = 65,770,127
Notice both answers equal 65,770,127
With that explanation out of the way, let's continue. Next, we take the number 65,770,127 and divide it by 2:
65,770,127 ÷ 2 = 32,885,063.5
If the quotient is a whole number, then 2 and 32,885,063.5 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 | 65,770,127 | |
| -1 | -65,770,127 |
Now, we try dividing 65,770,127 by 3:
65,770,127 ÷ 3 = 21,923,375.6667
If the quotient is a whole number, then 3 and 21,923,375.6667 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 | 65,770,127 | |
| -1 | -65,770,127 |
Let's try dividing by 4:
65,770,127 ÷ 4 = 16,442,531.75
If the quotient is a whole number, then 4 and 16,442,531.75 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 | 65,770,127 | |
| -1 | 65,770,127 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 37 | 527 | 629 | 1,147 | 3,373 | 19,499 | 57,341 | 104,563 | 124,801 | 1,777,571 | 2,121,617 | 3,868,831 | 65,770,127 |
| -1 | -17 | -31 | -37 | -527 | -629 | -1,147 | -3,373 | -19,499 | -57,341 | -104,563 | -124,801 | -1,777,571 | -2,121,617 | -3,868,831 | -65,770,127 |
