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 8,619,605, 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 | 8,619,605 | |
| -1 | -8,619,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,619,605.
Example:
1 x 8,619,605 = 8,619,605
and
-1 x -8,619,605 = 8,619,605
Notice both answers equal 8,619,605
With that explanation out of the way, let's continue. Next, we take the number 8,619,605 and divide it by 2:
8,619,605 ÷ 2 = 4,309,802.5
If the quotient is a whole number, then 2 and 4,309,802.5 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 | 8,619,605 | |
| -1 | -8,619,605 |
Now, we try dividing 8,619,605 by 3:
8,619,605 ÷ 3 = 2,873,201.6667
If the quotient is a whole number, then 3 and 2,873,201.6667 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 | 8,619,605 | |
| -1 | -8,619,605 |
Let's try dividing by 4:
8,619,605 ÷ 4 = 2,154,901.25
If the quotient is a whole number, then 4 and 2,154,901.25 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 | 8,619,605 | |
| -1 | 8,619,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 61 | 295 | 305 | 479 | 2,395 | 3,599 | 17,995 | 28,261 | 29,219 | 141,305 | 146,095 | 1,723,921 | 8,619,605 |
| -1 | -5 | -59 | -61 | -295 | -305 | -479 | -2,395 | -3,599 | -17,995 | -28,261 | -29,219 | -141,305 | -146,095 | -1,723,921 | -8,619,605 |
