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 5,618,405, 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 | 5,618,405 | |
| -1 | -5,618,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,618,405.
Example:
1 x 5,618,405 = 5,618,405
and
-1 x -5,618,405 = 5,618,405
Notice both answers equal 5,618,405
With that explanation out of the way, let's continue. Next, we take the number 5,618,405 and divide it by 2:
5,618,405 ÷ 2 = 2,809,202.5
If the quotient is a whole number, then 2 and 2,809,202.5 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 | 5,618,405 | |
| -1 | -5,618,405 |
Now, we try dividing 5,618,405 by 3:
5,618,405 ÷ 3 = 1,872,801.6667
If the quotient is a whole number, then 3 and 1,872,801.6667 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 | 5,618,405 | |
| -1 | -5,618,405 |
Let's try dividing by 4:
5,618,405 ÷ 4 = 1,404,601.25
If the quotient is a whole number, then 4 and 1,404,601.25 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 | 5,618,405 | |
| -1 | 5,618,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 109 | 169 | 305 | 545 | 793 | 845 | 1,417 | 3,965 | 6,649 | 7,085 | 10,309 | 18,421 | 33,245 | 51,545 | 86,437 | 92,105 | 432,185 | 1,123,681 | 5,618,405 |
| -1 | -5 | -13 | -61 | -65 | -109 | -169 | -305 | -545 | -793 | -845 | -1,417 | -3,965 | -6,649 | -7,085 | -10,309 | -18,421 | -33,245 | -51,545 | -86,437 | -92,105 | -432,185 | -1,123,681 | -5,618,405 |
