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 8,770,255, 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 | 8,770,255 | |
| -1 | -8,770,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,770,255.
Example:
1 x 8,770,255 = 8,770,255
and
-1 x -8,770,255 = 8,770,255
Notice both answers equal 8,770,255
With that explanation out of the way, let's continue. Next, we take the number 8,770,255 and divide it by 2:
8,770,255 ÷ 2 = 4,385,127.5
If the quotient is a whole number, then 2 and 4,385,127.5 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 | 8,770,255 | |
| -1 | -8,770,255 |
Now, we try dividing 8,770,255 by 3:
8,770,255 ÷ 3 = 2,923,418.3333
If the quotient is a whole number, then 3 and 2,923,418.3333 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 | 8,770,255 | |
| -1 | -8,770,255 |
Let's try dividing by 4:
8,770,255 ÷ 4 = 2,192,563.75
If the quotient is a whole number, then 4 and 2,192,563.75 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 | 8,770,255 | |
| -1 | 8,770,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 97 | 107 | 169 | 485 | 535 | 845 | 1,261 | 1,391 | 6,305 | 6,955 | 10,379 | 16,393 | 18,083 | 51,895 | 81,965 | 90,415 | 134,927 | 674,635 | 1,754,051 | 8,770,255 |
| -1 | -5 | -13 | -65 | -97 | -107 | -169 | -485 | -535 | -845 | -1,261 | -1,391 | -6,305 | -6,955 | -10,379 | -16,393 | -18,083 | -51,895 | -81,965 | -90,415 | -134,927 | -674,635 | -1,754,051 | -8,770,255 |
