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 8,586,875, 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 | 8,586,875 | |
| -1 | -8,586,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,586,875.
Example:
1 x 8,586,875 = 8,586,875
and
-1 x -8,586,875 = 8,586,875
Notice both answers equal 8,586,875
With that explanation out of the way, let's continue. Next, we take the number 8,586,875 and divide it by 2:
8,586,875 ÷ 2 = 4,293,437.5
If the quotient is a whole number, then 2 and 4,293,437.5 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 | 8,586,875 | |
| -1 | -8,586,875 |
Now, we try dividing 8,586,875 by 3:
8,586,875 ÷ 3 = 2,862,291.6667
If the quotient is a whole number, then 3 and 2,862,291.6667 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 | 8,586,875 | |
| -1 | -8,586,875 |
Let's try dividing by 4:
8,586,875 ÷ 4 = 2,146,718.75
If the quotient is a whole number, then 4 and 2,146,718.75 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 | 8,586,875 | |
| -1 | 8,586,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 625 | 1,249 | 1,375 | 6,245 | 6,875 | 13,739 | 31,225 | 68,695 | 156,125 | 343,475 | 780,625 | 1,717,375 | 8,586,875 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -625 | -1,249 | -1,375 | -6,245 | -6,875 | -13,739 | -31,225 | -68,695 | -156,125 | -343,475 | -780,625 | -1,717,375 | -8,586,875 |
