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 8,500,789, 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 | 8,500,789 | |
| -1 | -8,500,789 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,500,789.
Example:
1 x 8,500,789 = 8,500,789
and
-1 x -8,500,789 = 8,500,789
Notice both answers equal 8,500,789
With that explanation out of the way, let's continue. Next, we take the number 8,500,789 and divide it by 2:
8,500,789 ÷ 2 = 4,250,394.5
If the quotient is a whole number, then 2 and 4,250,394.5 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 | 8,500,789 | |
| -1 | -8,500,789 |
Now, we try dividing 8,500,789 by 3:
8,500,789 ÷ 3 = 2,833,596.3333
If the quotient is a whole number, then 3 and 2,833,596.3333 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 | 8,500,789 | |
| -1 | -8,500,789 |
Let's try dividing by 4:
8,500,789 ÷ 4 = 2,125,197.25
If the quotient is a whole number, then 4 and 2,125,197.25 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 | 8,500,789 | |
| -1 | 8,500,789 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 97 | 257 | 341 | 1,067 | 2,827 | 3,007 | 7,967 | 24,929 | 33,077 | 87,637 | 274,219 | 772,799 | 8,500,789 |
| -1 | -11 | -31 | -97 | -257 | -341 | -1,067 | -2,827 | -3,007 | -7,967 | -24,929 | -33,077 | -87,637 | -274,219 | -772,799 | -8,500,789 |
