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 5,219,005, 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 | 5,219,005 | |
| -1 | -5,219,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,219,005.
Example:
1 x 5,219,005 = 5,219,005
and
-1 x -5,219,005 = 5,219,005
Notice both answers equal 5,219,005
With that explanation out of the way, let's continue. Next, we take the number 5,219,005 and divide it by 2:
5,219,005 ÷ 2 = 2,609,502.5
If the quotient is a whole number, then 2 and 2,609,502.5 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 | 5,219,005 | |
| -1 | -5,219,005 |
Now, we try dividing 5,219,005 by 3:
5,219,005 ÷ 3 = 1,739,668.3333
If the quotient is a whole number, then 3 and 1,739,668.3333 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 | 5,219,005 | |
| -1 | -5,219,005 |
Let's try dividing by 4:
5,219,005 ÷ 4 = 1,304,751.25
If the quotient is a whole number, then 4 and 1,304,751.25 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 | 5,219,005 | |
| -1 | 5,219,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 341 | 1,705 | 3,061 | 15,305 | 33,671 | 94,891 | 168,355 | 474,455 | 1,043,801 | 5,219,005 |
| -1 | -5 | -11 | -31 | -55 | -155 | -341 | -1,705 | -3,061 | -15,305 | -33,671 | -94,891 | -168,355 | -474,455 | -1,043,801 | -5,219,005 |
