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 107,170,255, 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 | 107,170,255 | |
| -1 | -107,170,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 107,170,255.
Example:
1 x 107,170,255 = 107,170,255
and
-1 x -107,170,255 = 107,170,255
Notice both answers equal 107,170,255
With that explanation out of the way, let's continue. Next, we take the number 107,170,255 and divide it by 2:
107,170,255 ÷ 2 = 53,585,127.5
If the quotient is a whole number, then 2 and 53,585,127.5 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 | 107,170,255 | |
| -1 | -107,170,255 |
Now, we try dividing 107,170,255 by 3:
107,170,255 ÷ 3 = 35,723,418.3333
If the quotient is a whole number, then 3 and 35,723,418.3333 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 | 107,170,255 | |
| -1 | -107,170,255 |
Let's try dividing by 4:
107,170,255 ÷ 4 = 26,792,563.75
If the quotient is a whole number, then 4 and 26,792,563.75 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 | 107,170,255 | |
| -1 | 107,170,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 59 | 155 | 295 | 1,829 | 9,145 | 11,719 | 58,595 | 363,289 | 691,421 | 1,816,445 | 3,457,105 | 21,434,051 | 107,170,255 |
| -1 | -5 | -31 | -59 | -155 | -295 | -1,829 | -9,145 | -11,719 | -58,595 | -363,289 | -691,421 | -1,816,445 | -3,457,105 | -21,434,051 | -107,170,255 |
