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 8,583,155, 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 | 8,583,155 | |
| -1 | -8,583,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,583,155.
Example:
1 x 8,583,155 = 8,583,155
and
-1 x -8,583,155 = 8,583,155
Notice both answers equal 8,583,155
With that explanation out of the way, let's continue. Next, we take the number 8,583,155 and divide it by 2:
8,583,155 ÷ 2 = 4,291,577.5
If the quotient is a whole number, then 2 and 4,291,577.5 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 | 8,583,155 | |
| -1 | -8,583,155 |
Now, we try dividing 8,583,155 by 3:
8,583,155 ÷ 3 = 2,861,051.6667
If the quotient is a whole number, then 3 and 2,861,051.6667 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 | 8,583,155 | |
| -1 | -8,583,155 |
Let's try dividing by 4:
8,583,155 ÷ 4 = 2,145,788.75
If the quotient is a whole number, then 4 and 2,145,788.75 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 | 8,583,155 | |
| -1 | 8,583,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 12,907 | 64,535 | 90,349 | 245,233 | 451,745 | 1,226,165 | 1,716,631 | 8,583,155 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -12,907 | -64,535 | -90,349 | -245,233 | -451,745 | -1,226,165 | -1,716,631 | -8,583,155 |
