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 6,712,355, 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 | 6,712,355 | |
| -1 | -6,712,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,712,355.
Example:
1 x 6,712,355 = 6,712,355
and
-1 x -6,712,355 = 6,712,355
Notice both answers equal 6,712,355
With that explanation out of the way, let's continue. Next, we take the number 6,712,355 and divide it by 2:
6,712,355 ÷ 2 = 3,356,177.5
If the quotient is a whole number, then 2 and 3,356,177.5 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 | 6,712,355 | |
| -1 | -6,712,355 |
Now, we try dividing 6,712,355 by 3:
6,712,355 ÷ 3 = 2,237,451.6667
If the quotient is a whole number, then 3 and 2,237,451.6667 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 | 6,712,355 | |
| -1 | -6,712,355 |
Let's try dividing by 4:
6,712,355 ÷ 4 = 1,678,088.75
If the quotient is a whole number, then 4 and 1,678,088.75 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 | 6,712,355 | |
| -1 | 6,712,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 65 | 185 | 481 | 2,405 | 2,791 | 13,955 | 36,283 | 103,267 | 181,415 | 516,335 | 1,342,471 | 6,712,355 |
| -1 | -5 | -13 | -37 | -65 | -185 | -481 | -2,405 | -2,791 | -13,955 | -36,283 | -103,267 | -181,415 | -516,335 | -1,342,471 | -6,712,355 |
