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 5,405,405, 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 | 5,405,405 | |
| -1 | -5,405,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,405,405.
Example:
1 x 5,405,405 = 5,405,405
and
-1 x -5,405,405 = 5,405,405
Notice both answers equal 5,405,405
With that explanation out of the way, let's continue. Next, we take the number 5,405,405 and divide it by 2:
5,405,405 ÷ 2 = 2,702,702.5
If the quotient is a whole number, then 2 and 2,702,702.5 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 | 5,405,405 | |
| -1 | -5,405,405 |
Now, we try dividing 5,405,405 by 3:
5,405,405 ÷ 3 = 1,801,801.6667
If the quotient is a whole number, then 3 and 1,801,801.6667 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 | 5,405,405 | |
| -1 | -5,405,405 |
Let's try dividing by 4:
5,405,405 ÷ 4 = 1,351,351.25
If the quotient is a whole number, then 4 and 1,351,351.25 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 | 5,405,405 | |
| -1 | 5,405,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 1,615 | 3,347 | 16,735 | 56,899 | 63,593 | 284,495 | 317,965 | 1,081,081 | 5,405,405 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -1,615 | -3,347 | -16,735 | -56,899 | -63,593 | -284,495 | -317,965 | -1,081,081 | -5,405,405 |
