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 8,383,655, 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 | 8,383,655 | |
| -1 | -8,383,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,383,655.
Example:
1 x 8,383,655 = 8,383,655
and
-1 x -8,383,655 = 8,383,655
Notice both answers equal 8,383,655
With that explanation out of the way, let's continue. Next, we take the number 8,383,655 and divide it by 2:
8,383,655 ÷ 2 = 4,191,827.5
If the quotient is a whole number, then 2 and 4,191,827.5 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 | 8,383,655 | |
| -1 | -8,383,655 |
Now, we try dividing 8,383,655 by 3:
8,383,655 ÷ 3 = 2,794,551.6667
If the quotient is a whole number, then 3 and 2,794,551.6667 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 | 8,383,655 | |
| -1 | -8,383,655 |
Let's try dividing by 4:
8,383,655 ÷ 4 = 2,095,913.75
If the quotient is a whole number, then 4 and 2,095,913.75 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 | 8,383,655 | |
| -1 | 8,383,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 49 | 95 | 133 | 245 | 665 | 931 | 1,801 | 4,655 | 9,005 | 12,607 | 34,219 | 63,035 | 88,249 | 171,095 | 239,533 | 441,245 | 1,197,665 | 1,676,731 | 8,383,655 |
| -1 | -5 | -7 | -19 | -35 | -49 | -95 | -133 | -245 | -665 | -931 | -1,801 | -4,655 | -9,005 | -12,607 | -34,219 | -63,035 | -88,249 | -171,095 | -239,533 | -441,245 | -1,197,665 | -1,676,731 | -8,383,655 |
