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 8,501,255, 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 | 8,501,255 | |
| -1 | -8,501,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,501,255.
Example:
1 x 8,501,255 = 8,501,255
and
-1 x -8,501,255 = 8,501,255
Notice both answers equal 8,501,255
With that explanation out of the way, let's continue. Next, we take the number 8,501,255 and divide it by 2:
8,501,255 ÷ 2 = 4,250,627.5
If the quotient is a whole number, then 2 and 4,250,627.5 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 | 8,501,255 | |
| -1 | -8,501,255 |
Now, we try dividing 8,501,255 by 3:
8,501,255 ÷ 3 = 2,833,751.6667
If the quotient is a whole number, then 3 and 2,833,751.6667 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 | 8,501,255 | |
| -1 | -8,501,255 |
Let's try dividing by 4:
8,501,255 ÷ 4 = 2,125,313.75
If the quotient is a whole number, then 4 and 2,125,313.75 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 | 8,501,255 | |
| -1 | 8,501,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 4,957 | 24,785 | 34,699 | 173,495 | 242,893 | 1,214,465 | 1,700,251 | 8,501,255 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -4,957 | -24,785 | -34,699 | -173,495 | -242,893 | -1,214,465 | -1,700,251 | -8,501,255 |
