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 6,461,411, 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 | 6,461,411 | |
| -1 | -6,461,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,461,411.
Example:
1 x 6,461,411 = 6,461,411
and
-1 x -6,461,411 = 6,461,411
Notice both answers equal 6,461,411
With that explanation out of the way, let's continue. Next, we take the number 6,461,411 and divide it by 2:
6,461,411 ÷ 2 = 3,230,705.5
If the quotient is a whole number, then 2 and 3,230,705.5 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 | 6,461,411 | |
| -1 | -6,461,411 |
Now, we try dividing 6,461,411 by 3:
6,461,411 ÷ 3 = 2,153,803.6667
If the quotient is a whole number, then 3 and 2,153,803.6667 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 | 6,461,411 | |
| -1 | -6,461,411 |
Let's try dividing by 4:
6,461,411 ÷ 4 = 1,615,352.75
If the quotient is a whole number, then 4 and 1,615,352.75 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 | 6,461,411 | |
| -1 | 6,461,411 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 109 | 187 | 317 | 1,199 | 1,853 | 3,487 | 5,389 | 20,383 | 34,553 | 59,279 | 380,083 | 587,401 | 6,461,411 |
| -1 | -11 | -17 | -109 | -187 | -317 | -1,199 | -1,853 | -3,487 | -5,389 | -20,383 | -34,553 | -59,279 | -380,083 | -587,401 | -6,461,411 |
