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 10,168,255, 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 | 10,168,255 | |
| -1 | -10,168,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,168,255.
Example:
1 x 10,168,255 = 10,168,255
and
-1 x -10,168,255 = 10,168,255
Notice both answers equal 10,168,255
With that explanation out of the way, let's continue. Next, we take the number 10,168,255 and divide it by 2:
10,168,255 ÷ 2 = 5,084,127.5
If the quotient is a whole number, then 2 and 5,084,127.5 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 | 10,168,255 | |
| -1 | -10,168,255 |
Now, we try dividing 10,168,255 by 3:
10,168,255 ÷ 3 = 3,389,418.3333
If the quotient is a whole number, then 3 and 3,389,418.3333 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 | 10,168,255 | |
| -1 | -10,168,255 |
Let's try dividing by 4:
10,168,255 ÷ 4 = 2,542,063.75
If the quotient is a whole number, then 4 and 2,542,063.75 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 | 10,168,255 | |
| -1 | 10,168,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 127 | 239 | 335 | 635 | 1,195 | 8,509 | 16,013 | 30,353 | 42,545 | 80,065 | 151,765 | 2,033,651 | 10,168,255 |
| -1 | -5 | -67 | -127 | -239 | -335 | -635 | -1,195 | -8,509 | -16,013 | -30,353 | -42,545 | -80,065 | -151,765 | -2,033,651 | -10,168,255 |
