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 5,805,545, 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 | 5,805,545 | |
| -1 | -5,805,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,805,545.
Example:
1 x 5,805,545 = 5,805,545
and
-1 x -5,805,545 = 5,805,545
Notice both answers equal 5,805,545
With that explanation out of the way, let's continue. Next, we take the number 5,805,545 and divide it by 2:
5,805,545 ÷ 2 = 2,902,772.5
If the quotient is a whole number, then 2 and 2,902,772.5 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 | 5,805,545 | |
| -1 | -5,805,545 |
Now, we try dividing 5,805,545 by 3:
5,805,545 ÷ 3 = 1,935,181.6667
If the quotient is a whole number, then 3 and 1,935,181.6667 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 | 5,805,545 | |
| -1 | -5,805,545 |
Let's try dividing by 4:
5,805,545 ÷ 4 = 1,451,386.25
If the quotient is a whole number, then 4 and 1,451,386.25 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 | 5,805,545 | |
| -1 | 5,805,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 23 | 95 | 115 | 437 | 2,185 | 2,657 | 13,285 | 50,483 | 61,111 | 252,415 | 305,555 | 1,161,109 | 5,805,545 |
| -1 | -5 | -19 | -23 | -95 | -115 | -437 | -2,185 | -2,657 | -13,285 | -50,483 | -61,111 | -252,415 | -305,555 | -1,161,109 | -5,805,545 |
