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 5,818,805, 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 | 5,818,805 | |
| -1 | -5,818,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,818,805.
Example:
1 x 5,818,805 = 5,818,805
and
-1 x -5,818,805 = 5,818,805
Notice both answers equal 5,818,805
With that explanation out of the way, let's continue. Next, we take the number 5,818,805 and divide it by 2:
5,818,805 ÷ 2 = 2,909,402.5
If the quotient is a whole number, then 2 and 2,909,402.5 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 | 5,818,805 | |
| -1 | -5,818,805 |
Now, we try dividing 5,818,805 by 3:
5,818,805 ÷ 3 = 1,939,601.6667
If the quotient is a whole number, then 3 and 1,939,601.6667 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 | 5,818,805 | |
| -1 | -5,818,805 |
Let's try dividing by 4:
5,818,805 ÷ 4 = 1,454,701.25
If the quotient is a whole number, then 4 and 1,454,701.25 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 | 5,818,805 | |
| -1 | 5,818,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 71 | 185 | 355 | 443 | 2,215 | 2,627 | 13,135 | 16,391 | 31,453 | 81,955 | 157,265 | 1,163,761 | 5,818,805 |
| -1 | -5 | -37 | -71 | -185 | -355 | -443 | -2,215 | -2,627 | -13,135 | -16,391 | -31,453 | -81,955 | -157,265 | -1,163,761 | -5,818,805 |
