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 6,410,855, 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 | 6,410,855 | |
| -1 | -6,410,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,410,855.
Example:
1 x 6,410,855 = 6,410,855
and
-1 x -6,410,855 = 6,410,855
Notice both answers equal 6,410,855
With that explanation out of the way, let's continue. Next, we take the number 6,410,855 and divide it by 2:
6,410,855 ÷ 2 = 3,205,427.5
If the quotient is a whole number, then 2 and 3,205,427.5 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 | 6,410,855 | |
| -1 | -6,410,855 |
Now, we try dividing 6,410,855 by 3:
6,410,855 ÷ 3 = 2,136,951.6667
If the quotient is a whole number, then 3 and 2,136,951.6667 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 | 6,410,855 | |
| -1 | -6,410,855 |
Let's try dividing by 4:
6,410,855 ÷ 4 = 1,602,713.75
If the quotient is a whole number, then 4 and 1,602,713.75 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 | 6,410,855 | |
| -1 | 6,410,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 229 | 509 | 1,145 | 2,519 | 2,545 | 5,599 | 12,595 | 27,995 | 116,561 | 582,805 | 1,282,171 | 6,410,855 |
| -1 | -5 | -11 | -55 | -229 | -509 | -1,145 | -2,519 | -2,545 | -5,599 | -12,595 | -27,995 | -116,561 | -582,805 | -1,282,171 | -6,410,855 |
